There are a number of factors that can affect the success of a series of hair removal treatments, but generally, after each treatment, you’ll see a noticeable, permanent reduction in the number of hairs that regrow in the treatment area. Typically, it will require 4 – 6 treatments or more to permanently reduce the number of regrowing hairs by more than 80%, six months after the last treatment. Will my hair ever grow back? The short answer is no. Once the hair follicle is damaged, it cannot grow new hair. However, there are invariably a few hair follicles that manage to partially escape the laser during each treatment. Some of these follicles may be only stunned and will need to be retreated. Individual results may vary.
