How does laser hair removal work?
30 April 2013Laser treatment is one of the fastest-growing cosmetic treatments in the world but how does it work? Figures show it is the most popular procedure for women under 35, and is second only to Botox for those over 35 years of age.Laser treatment is used to safely remove unwanted or excess hair on any part of the body significantly reducing time spent on waxing, threading and plucking. The process of photothermolosys should only be performed by trained professionals in the presence of a dermatologist. A laser with a wavelength of 1064nm penetrates the skin to be absorbed by melanin in the hair follicle. Since the diameter of the beam is quite large, several follicles can be targeted at once. The light is then converted to heat energy which destroys the follicle, disrupting the hair matrix. It can take around five or six sessions to get rid of unwanted hair due to it having three different growth cycles. The damaged follicle may then grow but these will not be strong enough and will eventually fall off. Laser hair removal does not work on grey or white hair due to absence of melanin.
