A relatively new procedure laser hair removal is just over20 years old. While laser hair removal is typically done at a clinic there are now devices for consumers to use at home. Laser hair removal works by targeting darker areas which allow the lasers energy to be concentrated in one particular area without significant harm to the surrounding cells. Generally speaking, it is easier to target brown or black hairs because; these cells absorb the photon light from the laser better. Light skin also enhances the effectiveness of the laser because it is easier for the laser to find the target. As of 1997 the FDA approved laser hair removal treatment for the purpose of permanent hair reduction.
An important note in the FDA's definition of the word "Permanent" is that it does not actually mean permanent in the literal sense but, rather it means long term stable reduction. Therefore, several years later it is very possible for the hair to come back. The primary reason for laser hair removals wide growth is due to its minimal pain and fast results. It should be noted that laser hair removal typically takes 3-8 treatments for maximum effectiveness and in some patients additional treatments may be required.
The primary purpose of laser hair removal is to remove unwanted hair particularly on regions of the body such as upper lip, bikini line, armpits, and legs. However, the treatment can be used on any region of the body. Unfortunately for persons with white, gray, or blonde hair the treatment is generally not effective. Prior to treatment the patient will be given a pair of special goggles to wear to protect their eyes from the laser beam. The doctor performing the hair removal may also apply a topical anesthetic to reduce pain and discomfort. In some cases, a cooling gel or chilled tip is used to prevent damaging of cells around the follicles. Depending on the size of the area being treated the procedure can take several minutes to several hours.
