Laser hair removal
Lasers deliver an intense beam of light which are made up of a single wavelength or colour. Skin is essentially transparent to light in the wavelength range of 600 - 1100nm (nano meters), while melanin containing structures will absorb laser energy of this wavelength. It is therefore possible to target the hair follicle which has a concentration of melanin without affecting the surrounding area.
The light energy absorbed by the melanin pigment results in the rapid heating up of the hair follicle. This heat destroys the cells (papilla) responsible for hair growth. If adequate heating is achieved, then the follicle is permanently disabled resulting in a permanent reduction in hair growth.
Melanin in the epidermis also absorbs the energy and limits the depth of penetration of the laser light into the skin. Using a light wavelength of 808nm enables treatment of relatively dark skin as well as fair-skinned types. However, laser hair treatment is not suitable for Afro Caribbean or black skin complexions. Laser treatment is also ineffective in removal of white or grey hair. Electrolysis should be considered as an alternative treatment.
