If you're thinking about using laser hair removal to eradicate unwanted body or facial hair you'll want to know if the results will last. Although the only hair removal technique that is certified as permanent by the FDA is electrolysis, laser removal is usually advertised as being permanent as well. In addition, most who have used this procedure have experienced results lasting for years. There is, however, the risk of future regrowth because of the way the laser targets the hair. During the treatment the follicle's growth is made dormant. This means that the hair is not destroyed and may therefore commence regrowth at a later date.

The degree to which an individual enjoys long-term hair removal depends on a number of factors. Longer-lasting results are achieved when the procedure is performed on parts of the body with thinner skin, such as the armpit and bikini line. Areas such as the back or chin possess thicker layers of skin and, while they can still be treated effectively, require lasers that are programmed for such work. This type of precision is one of the countless reasons choosing a qualified dermatologist is vital to the success of the treatment.

If hair does, in fact, begin to grow again after a period of time, it usually comes in lighter and finer than the hair that was initially treated. If out-of-date equipment or incompatible laser types are used during treatment on light or fine hairs, there remains the possibility of complete regrowth. At present, there exist no lasers that can completely remove the fine, soft hairs that resemble peach fuzz and many types of lasers are found to be ineffective on these types of problem areas.

For the best and longest lasting hair removal results, there should be a number of sessions scheduled. These appointments, usually about 6-8, should be spaced about a month apart to allow for all hairs to be treated. As follicles follow a cyclical growth pattern not all hairs can be treated in one session. By spacing out the procedures the doctor can assure that all follicles will eventually be targeted, no matter their particular growth phase.

As is the case with any cosmetic or beauty procedure, some people will respond to laser hair removal treatments better than others. Because it is not possible to foresee your particular outcome it is recommended that potential recipients expect to undergo repeat appointments for retouching and improvements to the treated areas. These sessions, luckily, are usually required less and less as treatments progress.

A thorough consultation, conducted before, during and after your treatment, is a vital component for laser hair removal success. Discussing all aspects of the procedure is of great importance, especially if, after a few appointments, you're not happy with the progress or outcome. It is possible that there may be an unknown medical problem that causes the hair follicles to grow at an unusually rapid rate. If this is the case laser treatments would prove ineffective as the lasers cannot target the hairs as fast as new growth occurs. Of course, as always, the proficiency of the doctor performing the procedure will greatly impact the outcome. In addition, the type of laser utilized and the calibration of the beam will effect the results. Discussing these topics with your dermatologist prior to treatment is an important part of the whole laser hair removal experience.
