Does Laser Hair Removal Work?

Now that summer's here, many people are asking, "Does laser hair removal work?" First, let's briefly explore exactly how laser hair removal works. The procedure is usually performed by a medical doctor, often a plastic surgeon, who applies the laser to the area to be treated. The laser, which is a brief pulsating light beam, releases controlled energy pulses, each lasting less than a second. These pulses are aimed at the hair follicles beneath the skin, specifically the melanin, or dark pigment, of the hair.

The energy from the pulse heats the entire hair follicle, down to the root, and destroys the hair follicle. The surrounding skin is not damaged. All hairs have certain dormant periods are not growing all the time; the laser only affects hairs that are in their active growth phase. Subsequent treatments will target hair follicles that were not destroyed in the previous session or sessions. Usually between three and six treatments are needed to complete an area, depending on the heaviness of the hair growth.

The easiest areas to treat are those where hair growth is fairly light, like the upper lip. Persons with fairly light hair growth in the underarm areas, legs and bikini areas can also expect fairly quick results after only a few treatments. Persons with heavier hair growth or large areas like the back usually require more treatments. With only a few treatments, most growth is inhibited for at least several months. Repeated treatments can prevent hair regrowth for several years, or in some cases, forever.
