Laser therapy: indications and contraindications for the procedure that should not be neglected

Send

The first mention of lasers and their effect on the human body appeared in the 60s. Doctors and in our days did not come to a unanimous conclusion about the effectiveness of use, but one French doctor put the experience, took a skin biopsy with hair follicles, put them in a specific nutrient medium and irradiated them. The result was as follows: where the irradiation occurred in different doses, the most pronounced increase.

The first work on the use was published in 1992. Patients who underwent the course of therapy noted that the hair shaft became denser and the hair itself became more elastic. Since then, this trend has only been improved, and the number of satisfied patients has only increased.

Laser hair treatment is a method that is used as an adjunct to the main treatment. Is non-toxic, one of the newest methods, side effects have not been documented until today. Therapy can stop hair loss due to the effect of the beam. It has a rejuvenating effect, is able to restore the structure of the roots.

Important! Lasers with lower power were used more than 30 years ago so that wounds and burns healed faster and less painfully.

Contraindications

It is obvious that the proposed procedure can not fit all without exception. You should not expect a stunning effect if the hair fell out within 4 years or if the loss is caused by a specific disease. With the complete loss of hair, the dead follicles cannot be restored.

It is strictly forbidden to do treatment:

people with cancer,
with paralysis of the facial nerve,
during pregnancy
persons under the age of 12,
if there is a sunburn of the scalp or dermatitis,
with hemophilia.

Up to 12, the formation and development of the child's body is going on, any drugs during this period are prescribed carefully, and the laser can only harm!

Laser therapy is used to treat:

Cosmetological problems. These include baldness of various types, for example, infectious, diffuse, etc., structural changes in hair (fragility, graying).
Scalp Diseases (psoriasis, dermatitis, seborrhea, etc.).

Clinical treatment

For the procedure in the clinic during the procedure, the patient is under the device in the shape of a dome into which lasers are embedded. On the inside, 110 low-intensity lasers are mounted that are tuned to the hair and scalp treatments.

The procedure itself is painless. you can relax and even read something for 10-30 minutes. Lasers produce a pulsed, low-frequency light that has the ability to penetrate 8 mm under the scalp. The energy of the beam increases the blood circulation level, the level of oxygen and metabolism increases.

Updated blood flow can solve problems such as itching, dandruff, increased sebum secretion. About 80% of hair from the stage of rest go to the stage of active growth. In 50% of people, a significant increase is observed, and in 90% hair loss is normalized.

Home ways

The clinics use high-efficiency installations, the number of diodes in them is from 90 and above, but now you can often find laser combs that are intended for home use. There are disputes about what is better? It should be immediately noted that no such model will replace the treatment, but can be an excellent solution for prevention.

The market is filled with laser caps, various other equipment. Among the popular models:

Power Grow Comb. Laser comb, which includes a laser effect, infrared rays, soft vibration. Contains 14 LEDs of different frequencies. The average price is 850 rubles, the option is very budget, almost everyone can afford it.

Laser Hair RG-LB01. It is a vibrating massager, the manufacturer promises to increase the density of hair and stop hair loss. The device is much better than the previous one, but, unfortunately, it affected the cost. Cheaper than 15 thousand. P. find unlikely to succeed.

Efficiency

The results of the procedure can be manifested individually and depend on a variety of reasons, such as heredity, diseases, duration of hair loss. It is worth starting treatment as early as possible and not allowing the follicles to lose their vitality.

What can be obtained after treatment:

there will be an increase in local and general immunity,
relief of inflammatory processes,
normalization of the sebaceous and sweat glands,
scars resorption,
improved tissue nutrition.

After treatment, it is necessary to use paraben-free shampoos that do not destroy the hair structure.

Advantages and disadvantages

Analyzing the advantages and disadvantages, I would like to highlight the leading points.

Pros:

Performance. Of course, this procedure will not be left indifferent, since even in severe cases, recovery is almost always possible.
Security. Everything takes place under the supervision of a specialist and without surgery.
Lack of addiction and side effects.
Sustainability of the result.

Of the minuses can be noted the high cost and the need for multiple sessions. The average cost of the procedure in the salon is 1000 rubles, and a high-quality home appliance will cost 15-20 thousand rubles. However, the principle of price and quality works, so the result justifies the money spent.

More minuses of the procedure were not found, as well as negative reviews about it.

Conclusion

After the expiration of the 6-month trial, it was noted that 75% of women had increased hair in the frontal part, more than 85% of men also increased the amount of hair in the same place. 96% of women in the parietal part.

If you approach the treatment of this problem wisely, listen to the doctors and follow the suggested recommendations, after a couple of months you can notice how the hair becomes more presentable, a small fluff appears (which indicates that the growth has resumed), and then complete update that cannot be ignored. The effect is achieved gradually, you need to be patient.

Indications for laser therapy

- conditions provoked on the basis of immunodeficiency, as well as after surgery,

- diseases of autoimmune nature,

- pancreatitis (acute and chronic),

- an ulcer of organs such as the stomach and duodenum

- skin diseases: psoriasis, dermatosis,

- in dentistry it is also actively used to treat diseases of the oral cavity,

- treatment of adenoids in children,

- to increase the recovery functions of the body.

Also, laser therapy can be safely used to prevent most of the above diseases.

Please note that in cosmetology this therapy is also very relevant: it will help to cope with the problem of hair loss, aging skin, stretch marks, scars, as well as heal wounds in a short time.

What is laser hair removal

Remove hair from the face and body by the method of light irradiation. In order for the procedure to produce results, the hair must contain melanin, a coloring pigment. The amount of hair depends on its quantity. Melanin is of two fractions. Light, gray and red hair is not removed by laser, because they contain feomelanin, which does not absorb light, but reflects it. Dark shade of hair gives zumelanin. This compound absorbs the light wave and starts the thermolysis reaction. How it goes: the hair shaft heats up, then the heat is transferred down to the root, the follicle also heats up. Since the temperature is quite high, almost 70–80 ° C, the thermal reaction proceeds quickly, the vessels that brought the blood to the bulb become blocked, the nutrition stops, the hair atrophies and falls out.

How technology works

By the time one session of hair removal can last up to 40 minutes - this is if you are epilating a wide area, legs, for example. For some reason, it is a rather common misconception that the epilation of any part of the body takes no longer than 15 minutes. Masters are forced to explain: to achieve the desired result, you need to enlighten each hair not once, but 2-3 times, and this takes time.

Depending on the photo type (skin and hair color), the parameters of the epilation are set and the doctor begins the procedure. During the treatment of the skin, the handle-handle feels burning and pricking. After the procedure, a protective gel is applied. Hair does not disappear immediately, it takes time.

The essence of the method

Laser radiation is a concentrated light beam of sufficiently high power. During short flashes aimed at the subcutaneous part of the hair, energy is absorbed by cells containing melanin. As a result, heat is released, which damages the bulbs, without affecting the surrounding tissue.

Security

In addition to the pronounced efficiency, the laser has the necessary safety indicators. It acts strictly on the hair follicles with a penetration depth of not more than 3 mm. The risk of undesirable effects is minimized:

Burns.
Hair ingrowth
Enhanced growth.
Irritations.
Dryness

Outbreaks of laser radiation, although they have a thermal effect on the skin in the immediate vicinity of the hair follicle, do not affect the lymph nodes, blood vessels, and the reproductive organs.

Comfort and speed

Many say that the procedure is painful. However, the degree of discomfort is determined by the time of heat exposure. The pulse duration of up to 10 ms, which is generated by modern lasers, although it causes discomfort, but they are quite tolerant and are compared with pinching. In addition, many devices are already equipped with cooling systems that reduce thermal effects on fabrics.

Another undoubted advantage of laser hair removal, indirectly affecting its comfort is the speed of the procedure. Cleaning the area above the upper lip lasts only 3 minutes, the axillary hollows require 2 times more time, for the bikini area and shins it takes 20 and 30 minutes, respectively.

Laser hair removal is more comfortable than, for example, wax. It takes very little time, which also reduces the discomfort.

disadvantages

Along with clear advantages, the procedure has several disadvantages. The laser will not be able to remove too light or fluff hair, in which there is little melanin. The procedure will not have the effect and too dark or black people, because there will not be enough contrast to focus on the follicles. The radiation parameters and the type of laser should be selected taking into account the characteristics of the skin. Alexandrite laser, for example, covers 4 common photo types, so it fits most patients.

Laser hair removal can be carried out only by those who have no contraindications. It is better to reject the effects of light radiation in the following cases:

Individual intolerance.
Acute infections (including herpes).
Open injuries (wounds, abrasions).
Dermatological pathology (psoriasis, eczema, etc.).
Malignant neoplasms.
Varicose veins

Laser hair removal is not recommended during pregnancy and lactation, with decompensated cardiac pathology, diabetes and mental illness. Of the contraindications to the procedure, it is also worth noting the presence of light and gray hair, fresh tan with a prescription of not more than 2 weeks. And after the procedure for the same period will have to eliminate or minimize insolation (exclude a visit to the solarium, use SPF 50 sunscreen).

Among the shortcomings can be noted the need to repeat the laser hair removal, ie, the exchange rate effect. However, many cosmetic procedures have similar features, because their effectiveness is determined by the regularity and number of sessions performed. The cost of hair removal by the laser method is also quite high, but given the high efficiency and the ability to completely remove hair, the price seems quite reasonable.

The disadvantages of laser hair removal are probably not so serious, but in some cases they can also force you to choose a different technique.

Many who decide to remove hair in a particular area want to know what a laser epilation has pros and cons. The main advantage of the procedure is its high efficiency with a sufficient level of comfort. And of the specific disadvantages worth noting dependence on the color of hair and skin. All these features will determine the choice of the optimal method of removing unwanted body hair.

The advantages of laser hair removal over other methods of hair removal

There are quite a few ways in which you can remove unwanted hair. For example, a huge popularity is currently gaining shugaring - body epilation with the help of sugar paste.

Choosing shugaring or laser hair removal, you need to understand that sugar hair removal is painful and short-lived. Literally in 2-3 weeks the hair will begin to grow back, and you will have to constantly repeat the procedure.

Unconditional advantages of laser hair removal - painless and lasting effect. You no longer need to constantly worry about unwanted hairs on your body and waste time on regular unpleasant procedures.

Types of lasers for hair removal

There are several types of lasers that are used in cosmetology centers. Their main difference is in the wavelength, on which the final result and the ability to get the desired effect depend.

Diode laser. Wavelength - 810 nm. Universal view of the laser. Apply it on any type of skin not only to remove unwanted hair, but also to soften hard hair (treatment of hirsutism).
Alexandrite laser. The wavelength is 755 nm. Use on light and red hair, as well as used when working with sensitive skin. By the way, tattoo is removed with just such a laser.
Neodymium laser. A wavelength of 1063 nm, infrared light is present in the laser beam. Ideal for epilating dark hair, especially on dark skin. In addition, this laser is used to remove scars and acne.
Ruby laser. The wavelength is 694 nm. With its help, remove dark hair on the skin of light tones. It is also used to get rid of excessive pigmentation, as well as to remove tattoos applied with saturated color inks.

Can there be side effects and complications

Pondering whether to do laser hair removal, both women and men are concerned about the likelihood of side effects at the end of the procedure. Such a factor after the application of the laser method of hair removal and the truth is the place to be. However, if you follow certain rules, complications are quite easy to avoid. Consider the possible options and reasons for their manifestation.

The appearance of hyperemia on the skin. This can happen if the patient has a tendency to allergic reactions. This unpleasant manifestation will disappear in a few days.

Bruises and swelling. If a patient has recently sunbathed intensively (under the natural sun or in a tanning bed), then swelling or bruising can manifest itself on the treated area of the body.

This is due to the fact that the skin and so very recently received a significant dose of ultraviolet radiation, and another strong stream of light causes damage to it. That is why experts recommend to refrain from sunbathing before laser epilation.

Laser hair removal helped many women and men to become more self-confident, to get rid of the constant problem with annoying unwanted hairs and, importantly, saved time.

The main thing is not to be lazy to find a good cosmetic center and a professional, qualified cosmetologist. Pre-better to spend some time reading the reviews on the Internet, ask around with friends. This will save you from side effects and help you get a quality result.

Review of laser hair removal, as well as expert answers to various questions about laser hair removal, see the video.

Procedure mechanism

Laser therapy is based on the principle of photo-biotherapy, that is, the absorption of laser radiation cells. During the procedure, stimulation of metabolism and protein synthesis occurs.

Laser hair therapy in the clinic is carried out using an apparatus with built-in low-intensity lasers. Their power is tuned to the treatment of hair and scalp. The pulses penetrate into the skin by 8 mm. The energy of the beam improves blood circulation, increases the saturation of cells with oxygen, which contributes to an increase in metabolism.

Increased blood flow helps to get rid of several problems: itching, dandruff, increased sebum secretion. As a result of treatment, up to 80% of hair from the resting stage passes to the stage of active growth. In half of the cases there is an intensive growth, and in 90% there is a cessation of hair loss.

Therapy can be carried out at home after consulting a therapist or trichologist. For this purpose, use laser combs.

However, they are more often used as a prophylactic agent. Combs provide a light vibrating head massage and, with regular use, make the hair thicker and healthier. The time of exposure to the scalp at each point should be at least 4-5 seconds. To make hair grow faster, experts advise combing it against the growth line. This will increase the effect on the follicles.

What gives laser therapy for hair

A large number of lasers, which are used in cosmetology, affect skin components that absorb light. The main components are: melanin, hemoglobin and water.

Lasers are high and low power. High power lasers are very effective in treating many diseases, so they are used to eliminate follicles and eliminate unwanted hair, treatment of blood vessels and reduce wrinkles. High-power lasers, however, can burn and cut through fabric, and also emit a high level of heat.

Lasers of small power do not produce heat and are used in the treatment of injured tissue, and not for its further destruction. They are used as therapy against hair loss: the chromophore absorbs laser beams, which subsequently stimulate hair growth in the balding area due to blood circulation and oxygen flow, which stimulates the follicles at the cellular level, so the hair begins to grow faster and with increased density.

A number of doctors are convinced that the effect depends on the photochemical reaction during the cooperation of laser beams with the hair follicle. This reaction modifies the internal processing of cells and gives a signal for subsequent hair growth. Part of the hairs, which has already acquired a thin diameter, responds to therapy, but all the bald areas still do not disappear completely.

Types of laser hair removal and lasers

There are two groups of laser hair removal: contact and non-contact - depending on the type of nozzle. Non-contact epilation is effective for dark hair and fair skin. The laser wavelength is such that it acts on the melanin of the hair itself, and on the melanin of the skin; therefore, such epilation cannot be done by tanned and naturally dark people. In summer, this procedure is completely contraindicated due to possible burns and pigmentation.

Contact epilation with a diode laser does not have such effects. The laser wavelength is higher, and it only affects the hair pigment. The procedure is universal, suitable for dark, and for light hair and any skin color type. It will not cause negative consequences, even if it is carried out in the summer. Preparing for contact hair removal and growing hair is not necessary - the masters say that hair removal can be performed on smoothly shaved skin.

In alexandrite, ruby and part diode lasers, contactless nozzle is used. Modern diode and neodymium lasers use a contact nozzle: it comes into direct contact with the patient's skin during epilation. In general, contactless nozzles are outdated models of devices.

Hair removal lasers differ in two main characteristics: power and wavelength. The traditional and partly outdated classification includes:

In modern cosmetology, the heating of the skin can be neutralized with special nozzles (QOOL epilation), which makes it possible to refuse the use of anesthetics before the procedure.

Now they work in beauty salons on other, improved equipment:

AFT (Advanced Fluorescence Technology). Translated as "advanced fluorescent technology." The wavelength of light is from 755 to 1200 nm, that is completely safe for the skin. The nozzles use a special system of uniform distribution of radiation, so that the beam is not "peak", but rectangular. In a single highlight, several tufts of hair are irradiated, so the total exposure time of the lamp is less and the risk of burns is minimal. Discomfort from the procedure reduces the built-in cooling system. The technology has not yet received wide distribution in Russia, sometimes it is confused with diode laser hair removal.
IPLASER (1S Pro laser system). It works on a discharge lamp, like IPL, ELOS, SHR photosystems, but it has a narrow spectrum of light, like a laser. The light wavelength is from 755 to 1064 nm. The radiation is supplied in the mode of three pulses in one flash, which reduces the painfulness of the procedure. Acts on melanin of both hair and skin of any phototype, according to VI inclusive.

Portable diode lasers are recommended for home use. But they have low power, the beam penetrates shallowly, and their effect is short-lived.

Preparing for laser hair removal

Carefully consider the choice of salon, read the reviews on the work of the master, to which you go. Visit selected salons in person, women with experience are advised to look for places where they work on diode lasers. Sign up for a consultation with a dermatologist, cosmetologist and endocrinologist, it makes sense to visit a gynecologist if you are taking hormonal preparations. Discuss the possibility of laser hair removal with specialists, find out if you have any contraindications. The intensity of hair growth and the recovery rate of the bulbs depends on hormonal levels. If something is wrong, the hair will grow back in 3-4 months, and you can give money for the course as for a car - in Moscow, of course. This is from the words of a girl who has undergone 10 procedures, and without result.

At the consultation, the master talks about how to prepare for the procedure, whether you need to grow hair in the epilation zone or not. 2-3 mm length is usually needed for alexandrite laser, with diode and neodymium work on smooth skin. In any case, if you are used to removing hair with a root (wax, sugar, electric epilator), it is recommended to replace your depilation method with shaving for 3-4 weeks so that at least the hair roots will grow. The laser beam acts on melanin, and if there is no hair in the bulb, the procedure loses its meaning.

The recommendation not to sunbathe and not to attend a tanning salon a week before the session and a week after it is still relevant: it is better to refrain so that later no pigment spots form. 3 days before visiting the salon, discard the scrub and peeling for the part of the body that you will epilate.

If you are going to remove facial hair, a month before the procedure you can not do chemical peeling and any laser procedures.

Skin care after laser hair removal

As a precaution, it is better to refrain from physical exertion and visits to the bath for three days after the procedure, do not take a hot bath. Try not to let the sun hit the skin in the area of epilation, before going outside, use sunscreen with an SPF 50 or higher and do not visit the tanning bed for 7–10 days after each treatment. Soothing skin irritation will help soften the body cream.

In the intervals between treatments, the only possible way to remove hair is to shave, shugaring and waxing should be abandoned so that laser hair removal sessions will give results. It is possible to accelerate the loss of atrophied hairs by regularly rubbing the skin with a hard washcloth and scrubbing. Only you can begin to do this no sooner than 3 days after epilation.

Who needs hair therapy and for what signs

Until now, people are wondering if this type of treatment is suitable for everyone and what indications are needed for this:

Men and women who have been diagnosed with “androgenetic alopecia” or who have hereditary alopecia. Laser treatment in these cases is very effective with growth preparations.
Laser therapy is not very effective in the formation of bald patches, therefore, is more effective for the treatment of female diffuse hair loss.
It is necessary to pay attention to the fact that irradiation does not lead to a permanent result, therefore the patient should continue therapy so that the hairs continue to increase in volume.

Benefits and Cautions of Laser Hair Therapy

The main benefits of laser therapy are the following performance indicators:

an increase in blood flow to the scalp by 54% after the first session,
follicle stimulation
stop progressive hair loss (about 85% of patients),
increase the strength and elasticity of hairs,
rehabilitation after hair transplantation to a human being - as an aid to transplanted hairs in the healing process,
ensuring the desired dosage - rays penetrate measuredly into all areas of the scalp.

Contraindications to this procedure are: cancer, facial nerve paralysis, hemophilia, dermatitis, sunburn of the scalp, pregnancy and age up to 12 years.

Every person who decided on laser therapy must be aware that this procedure is completely safe and painless. The procedure is carried out throughout the year, with the course starting with three sessions per week, and later reduced to one session per month.

Possible results

The results of radiation therapy depend on many factors - genetics, the period of hair loss and whether this loss is a result of the disease. Undoubtedly, the effect would be better if, in addition to therapy, to additionally take medications that contain Minoxidil. When shampooing you should use shampoos that do not contain sodium sulfate.

The use of products that lead to weight loss, also recommended by doctors as part of the treatment. In addition, laser therapy should be carried out systematically, otherwise there is no need to wait for a positive result.

Of course, there are no guarantees that laser treatment will completely eliminate all problems, but there is still a positive outcome of events when using laser devices at home:

no change (slowing hair loss and growth not found),
slowing down or completely stopping hair loss (without growth),
hair restoration (hair loss stops, they become denser),
significant growth of hairs (stop loss and the acquisition of density).

In order to get an excellent result after laser therapy, it is recommended for people who have hair falling out for three years or less, since every year the sleeping follicles are harder to absorb rays. In addition, this treatment is not used in completely bald areas of the scalp, because it is not able to revive the dead follicles. In addition, laser irradiation will not be able to help cure hair loss, if it is at least somehow associated with existing diseases.

Depending on how quickly the person starts the treatment, how soon the body reacts and how well the patient follows the personal treatment plan, the result of the treatment will be visible.

About six weeks should elapse before hair loss begins to decrease or slow down dramatically. After eight to ten weeks, thin hairs sprout, and existing ones begin to grow and thicken more actively. After six months, there is a significant improvement and filling of the refined areas. After eight to twelve months, the patient's hair becomes strong and well-fed, and the scalp is no longer visible through the hairline.

Instruments for laser hair therapy

At this time, with the advent of a laser comb (HairMax LaserComb), this kind of treatment has become more accessible, but it is quite an expensive device that costs 550 u. e.

This comb has been approved since January 2007; it is a compact version of a large laser. With its help, laser treatment can be carried out at home. This device has teeth, with the help of which the rays penetrate the hair roots and stimulate their growth.

Also there is a device called Revage 670, it belongs to the class of laser diodes, was approved for use in cosmetology. It consists of 30 diodes, which are wrapped around 180 ° around the head, thereby increasing the connection of the laser beams with the follicles. The device is more effective at the end of therapy.

However, it is believed that the existing hair can prevent the effective impact of the laser beam on the entire area of the head. Revage 670 can be productive with female hair loss, where there are diffuse thinning.

Laser treatment can be safely used with other drugs (Propecia and Rogaine), but there are no contraindications that could interfere with hair transplantation.

Despite the fact that the use of laser hair therapy was approved for a long time, its long-term lasting effect has not been established.

What is the effectiveness of laser hair treatment?

The effectiveness of the procedure is based on the principle of photo-biotherapy. This principle is to stimulate protein synthesis and enhance cellular metabolism due to the absorption of laser light by cells.

For trichological treatment, the device generates pure low-intensity light of a wave of the same length, the absorption of which provides:

follicular cell growth
blood flow to the scalp,
the acceleration of the production of nutrients by the follicles,
activation of enzyme metabolism,
acceleration of biochemical reactions inside the cells,
launch of natural regeneration processes at the cellular level,
restoring the integrity of damaged tissues
reduction of inflammatory processes
increasing the level of protection from the effects of negative external factors.

How is laser hair therapy performed?

The duration of the session is usually about twenty minutes. During this time, the client is conveniently located in the chair, placing his head under a special device in the shape of a dome, in which about a hundred diodes are embedded. The device generates pulsed low-frequency light that penetrates under the scalp to a depth of no more than 8 mm. This leads to the fact that up to 70% of hair passes from the resting phase to the growth stage.

The duration of the course may vary depending on the clinical picture, as well as on the desired result. As a rule, it is recommended to undergo at least one procedure per week for 3-6 months (later, supporting sessions are possible to consolidate the achieved effect, or to repeat the course prescribed by trichologist).

Laser therapy session

In this case, the initial positive results will be noticeable after 8 weeks. The optimal schedule of sessions, taking into account the indications and combination with other methods, will be made by the specialist during the preliminary reception.

Why does hair need laser therapy?

Healthy hair condition depends on a variety of circumstances. The hair is adversely affected by the environment, repeated staining. This all destroys the structure of the follicles. Daily abundant hair loss can lead to the development of diseases such as baldness. If expensive shampoos do not cope with such a serious problem, then you need to turn to radical methods. One of these methods is laser therapy.

Laser hair therapy, procedure description

Laser therapy of the scalp is a revolution in the fight for beautiful and healthy hair.

On the human head is about 130 thousand hairs. In addition, more than 100 thousand bulbs are in a state of "sleep." Sparse hairs can be brought out of sleep mode and grown.

The treatment occurs with the use of cold lasers to enhance growth and reduce hair loss. This procedure occurs without the intervention of surgeons. The basis of laser therapy is the principle of photo-biotherapy, which is the absorption of cells by laser light. When this occurs, stimulation of cell metabolism and protein synthesis occurs.

The effect of laser light on hair growth has not yet been studied. Most likely, this is due to increased energy production. Laser light is formed into a red diode. Due to the fact that the red laser beam has a low absorbent index, laser treatment becomes a safe way to treat hair loss.

plazmolifting for hair loss

Low-power lasers were used 30 years ago in order to speed up the process of tightening wounds and burns. The principle of laser operation is the following: laser radiation affects the chromosomes of the skin and hair, thereby boosting the process of cell division and growth.

Laser treatment result

The result of laser therapy appears step by step. To achieve the best result, you must complete all courses of the session. The duration of one session is an average of 25-30 minutes. Improvements will be noticeable after eight weeks, but enhanced hair growth will begin after 5 months. This type of therapy has such advantages: hair after laser therapy becomes beautiful, silky and healthy, the strength and softness of the hair increases, the process of hair loss stops in 80% of patients, the light energy is equally distributed to all areas of the scalp.

Laser therapy is used in such cases: with psoriasis, atopic dermatitis.

There are some nuances that do not allow to achieve the desired result.

The history of low-intensity laser therapy

The effects of monochromatic and focused radiation on the human body began to be studied from the first days of the appearance of the laser itself - in the sixties of the last century. Doctors still have not come to unanimity regarding the effects of a low-intensity laser on the body, however, some efficacy has been observed in reducing pain in patients with rheumatoid arthritis, osteoarthritis, and other bone-joint apparatus pathologies.

The first studies conducted in the field of laser therapy were aimed at studying the effect of low-intensity laser radiation on blood. Experiments have shown that the green spectrum (with a wavelength of 532 nm and a power of 1 mW) promotes the binding of hemoglobin with oxygen in erythrocytes, but the ruby spectrum with a wavelength of 694nm does not produce this effect. Thus, it was concluded that when choosing an effective response to the cells and tissues of the body, the wavelength matters.

Why does hair need a laser

Readers are probably familiar with such a trend in cosmetology as laser hair removal, that is, hair removal using laser radiation. But studies have shown that certain parameters of the radiation wave can not only inhibit hair growth, but also activate it. Therefore, laser therapy for hair was effective in the treatment of androgenic alopecia, thinness and fragility of the hair shaft, in the fight against gray hair.

But before laser therapy began to be put into practice, various medical institutions in different countries carried out relevant studies. So, in the French city of Lyon, Dr. Yves Crassis organized research on the effect of laser doses on hair growth. He did a skin biopsy with hair follicles in 58 volunteers. The resulting bulbs placed in a nutrient medium, and every day irradiated with an infrared laser for 4 minutes for 10 days. Measurements performed every 3–4 days showed that where the irradiation was carried out with different doses of radiation, a more pronounced hair growth was observed.

Patients who have undergone a course of LT, noticed that the hair began to grow better, acquired additional luster, elasticity. The hair shaft became denser, thicker, which ensures the density of the strands.

Indications and Contraindications

In our country, laser therapy in the field of trichology is still a novelty. But, as the results of treatment show, this therapeutic method has good prospects. In addition to hair loss, laser treatment is used for folliculitis, seborrhea, infectious and fungal lesions of the hair.

Laser therapy is recommended for men suffering from androgenic alopecia, women with thin and brittle hair in the absence of the following contraindications:

Oncological diseases. Laser therapy can be especially dangerous with appropriate treatment, such as radiation and chemotherapy, which is known to lead to hair loss. The coat is usually gradually restored after the completion of treatment courses,
Facial paralysis,
Dermatitis. Irradiation can activate the inflammatory process,
Sunburn skin
Pregnancy
Children under 12 years old.

In the period of up to 12 years is the development and formation of the child's body. At this age, even drugs are prescribed selectively and with caution. And laser intervention is even more likely to harm a child.

Revage 670

A device is installed over the patient's head, which resembles a hair dryer for drying hair from the barber shops of the 70-80s. Only instead of warm air, it incorporates 30 diodes rotating around the head, emitting rays of low intensity. This is Revage 670.

The energy of the laser beam affects the active follicles, and awakens the sleepers. Laser therapy is carried out in combination with drugs. The procedure is completely painless and without discomfort.

The device is intended for physiotherapy cabinets, the procedure is appointed by the trichologist therapist for patients with thinned and weakened hair, partial hair loss, and is performed for 6–8 weeks 2 times a week.

HairMax LaserComb - laser comb and massager in one device

HairMax LaserComb - a device that represents a comb that emits laser beams of a given intensity. The HairMax LaserComb laser comb has been recognized by the FDA as an effective and safe means. The device is equipped with separate removable combs, which allows you to choose the most suitable comb for the patient's hair density.

The laser comb looks and looks like a massage hair brush, laser diodes are placed on the tips of the scallops. Thus, in the process of combing the scalp is massaged and the radiation is applied to the hair roots. During the procedure, blood circulation is improved, and as a result, the skin nutrition in the hair area. As a result, hair loss slows down, “dormant” follicles awaken, so that the hair thickens and becomes healthy.

When applying laser equipment yourself, avoid falling into the eyes. Do not use the irradiating device near the mirror, because the reflection of the beam of radiation is also not safe for the retina.

Therapy with well-chosen low-intensity laser radiation often helps men in the fight against androgenic alopecia. A quantum comb is used in the physiotherapy rooms of the trichological departments, but it can be applied with no less success at home. It is important only before using the device to carefully read the instructions and consult a doctor.

Such a device is not cheap - 30-50 thousand rubles. You can, of course, buy a cheaper Chinese equivalent, but such an acquisition will not give any guarantee of the effectiveness and safety of the device. Beauty, as is known, requires sacrifice, and first of all material.

Laser comb from the French manufacturer Gezatone combines laser radiation with vibratory massage, and thereby greatly increases the effectiveness of the procedure. This company produces not only laser-emitting products, but also a variety of facial and body care products. The cost of the instruments of this European company is lower than that of the Americans.

Blondes can withstand twice the intensity of laser radiation than brunettes. Before using the laser at home, consult a trichologist on the number of procedures and parameters of the radiation wave. Exceeding the intensity of the radiation, you can get the opposite effect.

Reviews of hair laser therapy

On the recommendation of the doctor bought a laser comb. Who expects instant results from her will be very disappointed. There were moments when I wanted to quit everything, but on the advice of the same doctor I had patience. After 2 months, he noticed that his hair began to fall out less, and a month later, he discovered the appearance of the first hairs on his bald head. Now I see that the money was well spent.

In the beauty salon I was told that the most effective laser hairbrush is Hairmax. The same device was recommended to me by the trichologist. Only in the fourth month I noticed the first results on hair restoration.

I bought a Hairmax comb. The manufacturer promised no side effects, but I feel deceived, because after each procedure the scalp is very itchy. I haven’t noticed any positive results yet.

There may be a lot of reasons for hair loss or their pathogenic condition. Here and hormonal disorders, and stress, and inflammatory processes. Therefore, the first thing to do is to cure the root cause of the disease, and only then solve the problem directly with the hair. Laser therapy is most effective when the hair falls out due to impaired blood circulation of the scalp. Concentrated beams of rays restore blood circulation in the body and oxygenation.
