Hair Removal with Laser
The treatment of various skin conditions has blossomed with laser due to the increasing understanding with its technology. One of the common application of laser is for hair removal. Although it is a common application of laser technology, it is not permanent and not for everyone. Laser technology works by emitting light at various wavelengths, energy output, and pulse widths. The wavelength used determines the skin structure it will affect such as veins, melanin, or water. Most lasers used for hair removal target melanin and are therefore designed to burn structures that contain melanin. The more melanin, the more damage. It makes sense that laser hair removal works best for light-skinned people with dark hair. As with electrolysis, hair follicles in the anagen phase are more easily destroyed than those in the telogen phase. Therefore, laser treatments for hair removal must be repeated. At this time it appears that laser treatment, while not causing permanent destruction of all hair follicles, does retard the regrowth of new hair.
