Laser Hair Removal:
Lasers have been effectively used to remove unwanted hair for some time. The laser energy is transferred to the hair follicle to selectively destroy the hair germination apparatus, resulting in cessation of hair growth.
The process relies on the melanin (dark) pigment in the hair shaft that absorbes the light energy, which is converted to heat and then transferred to the hair follicle. For this reason, the darker the hair, the better, and more efficient the treatment will be.
For the best result, it is important to shave the hair just before the treatment. This allows the hair shaft to be even with the skin for best absorption of the laser energy. Tweezing or waxing causes the hair shaft to be broken or removed from below the surface of the skin so that it is not directly in the path of the laser light. It is therefore not advisable to tweeze or wax for several weeks prior to the laser treatment. Melanin pigment in the skin from tanning can interfere with absorption of the laser light by the melanin in the hair shaft. For this reason, it is important to avoid sun exposure or suntanning for at least one month prior to laser hair treatment. Laser treatment to tanned skin can cause loss of pigment in the skin.
