By now you've seen the billboards and the commercials touting laser hair removal as the next big thing in grooming, but how does it really work. And how well does it work? Here's a look at the workings behind laser hair removal.

Melanin is the secret to laser hair removal. The lasers target melanin in darkly pigmented hair and kill it at the root. These hairs will subsequently fall out.

You are best suited for laser hair removal if you have dark hair and light skin. Those with light hair or dark skin most likely should not undergo the treatment. The center you go to will also advise you to avoid any sunbathing while the treatment is ongoing.

The procedure is not usually significantly painful, but there can be some discomfort. Most will say it feels like a rubber band snapping against their skin. If you are feeling a significant amount of pain, the operator can give you a topical numbing cream to put on the area prior to treatment.

Hair goes through various phases, with some being present and others being dormant at a certain time. Thus it is necessary to undergo several treatments, usually about a month apart, in order to target the hairs in every phase.

Laser hair removal is considered permanent hair reduction. These means that you may still have some hairs or may see some regrowth over time. The only method that is truly permanent hair removal is electrolysis. Ask your treatment center if they offer a period of free touchups.

There is some risk involved with laser hair removal. While it is rare, some people will experience burns or hyperpigmentation of the treated skin. Ask your provider any questions you might have and find out what their percentages of complications are.

Laser hair removal is effective and simple, but it is not entirely risk free. Be sure to know the facts and find a skilled professional, rather than just the clinic that offers the lowest price.
