A lot of people are under the mistaken impression that laser hair treatments are guaranteed to permanently eliminate all unwanted hair from their treated facial and body areas. The truth of the matter, however, is that these procedures are designed to significantly reduce the appearance of hair on a semi-permanent to permanent basis. Thus, they tend to be a lot more effective than they are given credit for. These procedures work by targeting individual hair follicles with controlled pulses of laser light. After sufficient follicular damage is caused, the targeted follicles will die off and fewer or no hairs will be produced in the future. If you have very light-colored and fine hairs across the treatment zone, you can expect to receive rapid and long-lasting results. If your hair is very dark, coarse and stubborn, however, you may need a larger number of treatments to reach your cosmetic goals. Moreover, robust hair follicles also have a higher likelihood of recovering from these treatments in the future.
