The perfect candidate for laser hair removal is someone with fair skin and dark hair. Since the laser is drawn to darker pigments, it can be more effective when the hair is much darker than the skin -- more energy is concentrated on the hair follicles, which disables them more fully. However, with a skilled technician and current technology, just about anyone is a candidate for laser hair removal. It will be less effective on grey or very light hair, or on hair that is very close in color to your skin tone.
