Laser hair removal is a treatment that is used to remove unwanted body hair. The laser emits a concentrated beam of light, which is absorbed by the pigment in the hair. The light energy is then converted to heat, which damages the sacs in the hair follicles that produce hairs. By using this laser treatment it damages the follicle and delays future hair growth. This damage inhibits or delays future hair growth. Although laser hair removal delays hair growth for long periods, it may not result in permanent hair removal.
