Laser hair removal is the process of removing unwanted hair by means of exposure to pulses of laser light that destroy the hair follicle. It had been performed experimentally for about twenty years before becoming commercially available in the mid-1990s. The efficacy of laser hair removal is now generally accepted in the dermatology community, and laser hair removal is widely practiced in clinics. Many reviews of laser hair removal methods, safety, and efficacy have been published in the dermatology literature.
The primary principle behind laser hair removal is selective photothermolysis (SPTL), the matching of a specific wavelength of light and pulse duration to obtain optimal effect on a targeted tissue with minimal effect on surrounding tissue (gets rid of the hair and doesn’t damage the skin). Lasers can cause localized damage by selectively heating dark target matter, melanin (the color you see in skin and hair), in the area that causes hair growth, the follicle, while not heating the rest of the skin. Light is absorbed by dark objects, so laser energy can be absorbed by dark material in the skin, but with much more speed and intensity.
Hair grows in several phases (anagen, telogen, catagen) and a laser can only affect the currently active growing hair follicles (early anagen). Hence, several sessions are needed to stop hair growth due to the different phases of growth during each treatment.
Multiple treatments depending on the type of hair and skin color have been shown to provide long-term reduction of hair. The number of sessions depends on various parameters, including the area of the body being treated, skin color, coarseness of hair, reason for hirsutism, and sex. Coarse dark hair on light skin is easiest to treat. Certain areas (notably men’s faces) may require considerably more treatments to achieve desired results.
Laser does not work well on light-colored hair, red hair, grey hair, white hair, as well as fine hair of any color, such as vellus.
Typically the shedding of the treated hairs takes about two to three weeks. These hairs should be allowed to fall out on their own and should not be manipulated by the patient for certain reasons, chiefly to avoid infections. Pulling hairs after a session can be more painful as well as counteract the effects of the treatment.
Hair removal lasers are effective treatment for pseudofolliculitis barbae, commonly called “ingrown hairs” or “shaving bumps”. They have recently been reported as helpful treatment for pilonidal cysts, since they eliminate the ingrown hairs that produce the troublesome foreign body reactions in this malady.
We use a state of the art Palomar Vectus hair removal laser. Utilizing the newest technology, the Vectus Laser is considered the fastest and most effective of its kind. Its functional wavelength of 800 nm is considered the ideal level for permanent body hair removal. The features of the Laser are:High peak Power, short pulse capability, Advanced contact cooling for increased client comfort, large spot side for more precise treatment areas, a more uniform beam without hotspots for less overlap and better performance. It is the fastest in hair removal, that provides permanent hair reduction for a wide range of skin and hair types!
