Laser hair removal treatment removes unwanted hair by pulse of laser light, which destroys the hair follicle. This treatment was first done experimentally about twenty years ago and became commercially available around mid 1990. Selective photothermolysis is the main principle behind laser hair removal treatment.
Earlier generation laser treatments were very slow, painful, and only worked on very dark hair on lighter skin. Now, however, laser treatment is much better. Several hair removal treatments are available that are not painful and are designed for various skin and hair types. For permanent hair removal by laser, several sessions are needed.
You may be wondering which laser is the best for hair removal. Actually, there is no single best laser that can be used for this treatment. The best one for you depends on things like your skin type, hair color, etc. The effectiveness of laser treatments will vary from person to person according to their different skin and hair types.
