Many girls began to suffer from the season of exposed arms and exposed thighs. Their body hair is exuberant, and they don’t look good in skirts. If they cannot be cleaned with depilatory cream, then forget it. Going to a beauty salon for laser hair removal feels no effect. Should the hair grow or will it continue to grow? In fact, it is not invalid. It may be that their beauticians are inexperienced, or their equipment is ineffective.
The most common and effective hair removal device at present is the 808 laser hair removal device, which acts on the skin surface by emitting 808nm laser. The laser passes through the skin until it reaches the highest concentration of melanin in the hair shaft.
Laser hair removal requires thorough hair removal according to the course of treatment. The growth cycle of hair is divided into growth period, decay period and dormancy period. The hair follicle depilation effect is the best in the growth period.
During the growth period, the hair growth is active, the melanocytes divide vigorously, and the melanin content reaches the peak. In the anagen phase, hair growth stagnates, the number of capillaries decreases, the dermal papilla shrinks, and melanocytes stop producing melanin. When at rest, the hair matrix separates from the nipple, and the hair falls off.
The principle of laser hair removal machine is to use the selective absorption of melanin to heat the hair follicles above 75 degrees Celsius to inactivate the hair follicles (hair papilla), thereby achieving the effect of hair removal. The melanin content in the hair follicle reaches its peak during the growth period, so only the hair in the growth period can achieve the expected therapeutic effect after each irradiation.
