What It Does : Using laser light energy to penetrate the hair shaft, it actually kills the hair root. This doesn't kill the follicle (the place where hair growth starts). So technically, another hair can grow in its place, but it's difficult. That means results of laser hair removal last a fairly long time.
How Long It Takes : Roughly 30 minutes per treatment, up to eight treatments needed.
Best For : Removing or reducing hair on back, chest, stomach, shoulders, and genital area. Works best on light skin with dark hair; not suitable for blond or white hair. Black skin responds well to only one type of laser, the Nd: YAG.
Cost : $400-500 per treatment.
Lasting Result : After all laser hair removal treatments are completed, results could be almost permanent, with touch-up treatments annually or biannually to maintain results.
Expert Comments : "Most men utilize laser hair removal for the back, upper arms, and chest and most want it thinned out, not removed -- something which lasers can easily accomplish," says Goldberg. In fact, other than electrolysis, laser hair removal is the only hair removal treatment that allows for thinning, rather than complete removal. While the average man needs five to seven sessions, as men age, more hair grows, especially on their backs, says Goldberg. As such, touch-up laser hair removal treatments are usually needed on average once a year.
