Removal method: Some women use tweezers to remove excess eyebrows and facial hair. This hair removal method is simple and cost-free, but the local pain is obvious during hair removal. Pulling out can't fundamentally destroy the hairball part. After 2-8 weeks, the hair will grow again. In addition, repeated plucking will not only lead to hair follicle allergic reaction, but also leave scars for people with scar constitution.

Chemical hair removal method: At present, chemical hair removal agents used for hair removal include depilatory cream, depilatory cream and depilatory liquid. In this method, chemical agents are applied to local skin, and their chemical components can immediately corrode and dissolve hair shafts, thus achieving the effect of hair removal quickly. Because the hair roots under the epidermis can also be dissolved by chemical depilatory, compared with shaving, the hair growth rate is slow and the effect can last for more than 2 weeks.

Electrolytic hair removal method: insert tiny metal needles around each hair follicle, apply current, cause electrolytic reaction of tissue, destroy hair follicles and hair balls, and achieve the purpose of hair removal. This method belongs to permanent hair removal. After many electrolytic treatments, the hair follicles and hair balls in the "growth center" of hair can be destroyed, and the effect of hair removal can be achieved. Its biggest shortcomings are time-consuming, obvious pain and high cost.

Laser hair removal method: the international beauty industry believes that laser hair removal is a revolutionary high-tech beauty medical technology. It is the most advanced permanent hair removal method at present. Modern laser technology has developed by leaps and bounds. At present, the most respected method is "photon hair removal". The principle of hair removal is the same as other lasers. It uses high-energy photon output to selectively destroy hair follicle tissue without damaging skin and sweat glands, and can effectively remove hair of various parts, colors and textures of the body.

Extended data

Laser hair removal is an important discovery of modern photothermal science. Using the principle of "selective photothermal effect", melanocytes in hair follicles absorb light with a specific wavelength and convert it into heat energy that destroys hair follicle tissue, thus making hair lose its regeneration ability without damaging surrounding tissues, with slight pain. Laser hair removal is a safe, fast and long-lasting hair removal technology at present.

Because the growth cycle of hair follicles is different, hair in any part has some potential ability to grow long hair, that is, incubation period. Light is effective for growing hair follicles, but not for dormant hair follicles. Therefore, according to the characteristics of hair growth in different parts, it is generally necessary to go through multiple treatments to remove excess hair in various parts of the body.
