To permanently destroy hair follicles, the temperature of the germ cells needs to be raised high enough to cause coagulation, thus preventing further regrowth. It's very safe and in just a fraction of a second, hundreds of hairs can be treated. The treatment is effective in the anagen (growth) stage only, hence several treatments are required. An immediate result can be seen on the visible part of the hair indicating the success of the treatment that both the therapist and the client can see. A pain free permanent hair removal alternative to laser hair removal.
