Recently, more and more people are coming to the clinic to see hair loss, and even patients suffering from other skin diseases such as dermatitis and acne have to turn around and ask one more question when they walk out of the clinic with their prescriptions: “Professor Zhang, I think I have lost a lot of hair lately, why don’t you take a look at me?” Not only that, we also found that people with hair loss are getting younger and younger, and even more so for men and women, which shows that the problem of hair loss is really getting more and more serious. Not yet become strong, first become bald? Others are getting rid of their hair and you are going bald? Androgenetic alopecia, neurogenic alopecia, nutritional alopecia are not clearly distinguishable, basic medication topical minoxidil, internal spironolactone (female) / finasteride (male) do you understand? Quickly click to make up for the basic others off, you lose hair? Although most people have abandoned the misconception that “rubbing ginger on the scalp can grow hair”, but people always want to use a more simple and effective way to solve the problem, a so-called “activation of the hair follicle, new hair” of the United States theradome hair growth helmet It is a kind of American theradome hair growth helmet which claims to “activate hair follicles and regrow hair”. 80 diodes, 678nm unique wavelength, twenty minutes a day can penetrate deep into the hair follicle, activate the root of the hair follicle, let the hair new life? Please control your new hands from the double 11 do not rush to order! Take a closer look at the official website of Silhouette and find that this helmet is aimed at seborrheic alopecia. Seborrheic alopecia, also known as androgenic baldness, is due to excessive androgens, transforming excess testosterone into dihydrotestosterone (DHT) under the action of 5α reductase (an enzyme) in the body. Dihydrotestosterone (DHT) is a hair follicle killer, constantly eroding hair follicles, causing new hair to become thin, fragile, easy to break and easy to lose. At the same time, DHT constantly stimulates the sebaceous glands to produce unbalanced oil, which intensifies the oiliness and aggravates hair loss. After reviewing the literature, we found that the main role of laser hair growth cap is to improve local blood circulation in the scalp, improve the microenvironment of hair follicle growth and thus promote hair growth. Studies have shown that 650~900nm with an energy density of 5mW/cm is the most effective energy parameter for the treatment of hair loss, and the therapeutic effect of laser combined with 5% minoxidil tincture on patients with seborrheic alopecia was 85.7%, compared with 53.3% for the laser irradiation group alone. Therefore, the efficacy of using laser hair growth cap alone to treat seborrheic alopecia or other types of hair loss is still debatable. Why not stay up less and do more scalp massage?
