Hair removal is an eternal topic for beauty lovers, and it is a matter of concern as to what kind of hair removal is used. The commonly used hair removal methods are: plucking, scraping, waxing film method, laser or intense light, electrolysis, hair removal cream and anti-androgen drugs. These methods have their own advantages and disadvantages. At present, laser or intense light hair removal is gaining more and more popularity among beauty lovers because of its good effect and little side effects. However, some people have certain misconceptions about it. Myth 1: Laser or intense light can achieve the effect of permanent hair removal. The current laser or intense light treatment instrument has the function of “permanent” hair removal, so many people will be misunderstood as no hair growth for life after treatment, in fact, this “permanent” and not the real sense of permanent. The FDA’s understanding of “permanent” hair removal is that no more hair grows during a hair growth cycle after laser or intense light treatment. In general, hair removal rates can reach 90% after multiple laser or light treatments, although the effectiveness of this treatment is influenced by many factors. Myth 2: Laser or intense light hair removal is only needed once. It takes several treatments to achieve long-lasting hair removal results. There are cycles of hair growth, including anagen, regression and diapause. Laser or intense light is only effective on the hair follicles in the anagen phase, but not on the hairs in the regressive and resting phases, and it will only work when these hairs are transferred to the anagen phase, so multiple treatments are needed for the effect to be obvious. Misconception 3: The effect of laser hair removal is the same for all people and all parts. The efficacy of laser hair removal is different for different individuals and different parts of the body. The factors affecting the individual are: endocrine dysfunction, different anatomical parts, skin chroma, hair color, hair consistency, hair growth cycle and hair follicle depth, etc. Generally speaking, the effect is good for white skin and black hair. Myth 4: The remaining hairs will become darker and thicker after laser hair removal. Actually no, the remaining hairs after laser or intense light treatment will become finer and lighter in color. Laser or intense light hair removal is a good choice, but you still need to have a proper understanding of it before treatment.
