Laser hair removal for unwanted hair has become one of the most common cosmetic procedure. Laser hair removal utilizes beams of highly concentrated light designed to selectively penetrate into the hair follicles, to be absorbed by the pigment in the hair follicles and to destroy the hair within that hair follicle. A variety of lasers and light sources have been developed that may be employed in laser hair removal.
The procedure was originally described to be performed on dark hairs on light skin; newer technologies have made the procedure safer for patients with darker skin and those of colour.
Various types of lasers are utilized with laser hair removal – the most common of which are alexandrite, diode, Neodymium YAG and intense pulsed light sources.
