Laser hair removal is a technique that uses beams of highly concentrated light to penetrate the hair follicles. The light is absorbed by pigment in the follicles and destroys the hair within them. Laser hair removal is among the most commonly performed cosmetic procedures.
Concealers are temporary hair cosmetics, good for thinning hair and as temporary solution such as before going to party. They require regular care and expense. They are not cheap either.
