1. The origin of androgenetic alopecia treated by low-energy laser therapy instrument


In 1964, in order to study whether the ruby laser was carcinogenic, a Hungarian doctor conducted a low-energy laser experiment on small mice, and unexpectedly found that the laser not only did not cause cancer, but also promoted the growth of mouse back hair. This is the first time that low-energy laser therapy (LLLT) has been confirmed. ) photobiostimulation.


In 2007, the U.S. Food and Drug Administration (FDA) approved the first home-use low-energy laser treatment device, deeming it safe and effective for treating androgenetic alopecia.


In 2010, a low-energy laser treatment device for home use passed FDA certification, which is the first low-energy laser helmet product approved by the FDA for the treatment of androgenetic alopecia.

Today, low-energy laser therapy equipment has become a better way to treat androgenetic alopecia, and is recommended by many countries and regions in the world for the treatment of androgenetic alopecia.


  1. Product classification of low-energy laser therapy devices in the treatment of androgenetic alopecia


Throughout the application of low-energy laser therapeutic instruments in the treatment of androgenetic alopecia, there are currently three types of products.


The first category: low-energy laser therapy comb. This type of product is generally equipped with less than 20 weak laser lights. When using it, you need to hold a hair care comb to irradiate the hair loss area area by area. The single use time is long, easy to fatigue, and it is difficult to persist in using it.


The second category: stand-alone version of low-energy laser therapy  hair growth helmet. The shape of this type of product is similar to a helmet, with 60-200 low-energy laser lights inlaid inside, with a fixed lighting interval (once every other day) and a fixed use time (20 minutes each time).


The third category: intelligent low-energy laser therapy (hair growth) helmet. This type of product has an exclusive smart APP, which can voice remind the light to record the number of light, monitor the temperature and oiliness of the scalp, etc., and can realize the remote guidance of the hair loss doctor through human-computer interaction, and customize the exclusive light mode and personalized treatment according to the specific situation of the patient's hair loss Program


  1. The principle of low-energy laser therapy instrument to promote hair growth


The low-energy laser therapy instrument is equipped with several 650nm 5mW low-energy laser lamps. The laser light of this wavelength can penetrate the surface layer of the scalp for 3~5mm and reach the depth of the hair follicle, and can connect with the respiratory chain target of the mitochondria in the hair follicle. C oxidase performs a photolysis reaction, thereby releasing more NO (nitric oxide), ROS (reactive oxygen species) and ATP (adenosine triphosphate, energy), which accelerates the metabolism of the hair and the thermal effect of the laser will accelerate hair follicles. Tissue blood flow velocity, NO (nitric oxide) will also play a role in dilating blood vessels, and the cell endothelial growth factor stimulated by laser can promote new capillaries and provide more nutrients for hair follicles. Under the action of the above-mentioned multiple mechanisms, it is expected that the atrophic hair follicles will be stimulated to redevelop, thereby promoting hair growth.


  1. Usage of low-energy laser therapy instrument (take hair growth helmet as an example)

Turn on the power of the low-energy laser therapy device, put on the helmet, let the scalp of the hair loss site receive direct light, and wear it every other day for 25-35 minutes each time. Pay attention to use it when the hair is dry, and do not stay up late.


  1. The best time to use low-energy laser therapy equipment

Clinical efficacy data show that persistent and correct use of low-energy laser therapy instruments has a significant effect on hair loss, and the therapeutic effect is related to the degree of hair loss, course of treatment and age. Generally speaking, the earlier the hair loss treatment is, the better the curative effect is (note that it is an adult), the longer the treatment course is, the better the therapeutic effect is (generally, more than 1 year of regular use can achieve the best effect), and the more severe the hair loss, the worse the therapeutic effect will be.

hair loss treatment

Early detection and early treatment should be achieved, and regular light should be adhered to for a long time without staying up late. Generally speaking, the combination of low-energy laser therapy instrument and minoxidil or finasteride tablets has a more significant therapeutic effect.


  1. The effect of low-energy laser therapy instrument and the change of disabling it

As a second-line product for the treatment of androgenetic alopecia, although the curative effect of the low-energy laser therapy device cannot be compared with minoxidil and anandramide tablets, because it is a physical therapy, it is far behind in terms of side effects lower than the above two drugs. In addition, for patients who are unwilling to take drugs for a long time, it is an ideal choice to use low-energy laser therapy equipment to treat androgenetic alopecia. Furthermore, for those who are ineffective in drug treatment, low-energy laser therapy instrument is also an ideal choice. Final suggestion: The combination of low-energy laser therapy instrument and minoxidil or finasteride tablets has a more significant therapeutic effect.

Generally speaking, the first half month to 1 month is the effective time of oil control, 2-3 months is the effective time of solid hair, 3-6 months is the effective time of promoting hair growth, and 1-1.5 years later is the continuous hair maintenance period .

After stopping the light, there will be different degrees of relapse. After entering the continuous maintenance period, the light frequency can be gradually reduced, and it is not recommended to stop using it.

  1. Side effects of low-energy laser therapy equipment

Adverse reaction reports focused on local skin symptoms of the scalp in the irradiated area. About 1/3 of the patients had obvious discomfort after using LLLT for the first time. These discomforts included dry skin, itching, redness, tight scalp, acne, hives and irritation sexual feeling. But it will gradually improve over time, and the proportion will drop to 5.4% at 90 days, which will not affect the treatment process.


  1. Does the low-energy laser therapy device need to be used for a long time?

From the current medical level, androgenetic alopecia is a chronic, incurable disease related to multiple factors. The treatment of androgenetic alopecia is a lifetime, therefore, long-term laser hair growth helmet treatment is required. If you insist on regular use for more than 1 year, you can appropriately reduce the frequency of use according to your own situation, and it will hardly cause inconvenience to your life. In addition, science and technology are constantly developing, and there may be better ways to treat androgenetic alopecia in medicine.


  1. Will the low-energy laser therapy device harm the health?

Each low-energy laser therapy device has been evaluated for safety and effectiveness before receiving the country's marketing batch number, so it will not affect your health. In addition, this type of product belongs to pure physical therapy, with low power, it can only penetrate 3-5mm scalp surface cells, and cannot reach deeper tissues.
