Are you frustrated with facial or body hair? If you are, perhaps you need to speak with a cosmetic or beauty expert on how to deal with the problem permanently. The problem with hair is that even if you shave it or wax it off, it grows back after some time. If you want this problem to go away forever, you may have to consider going for laser hair removal sessions.

Laser hair removal is getting more and more popular these days because it is an effective way of removing hair with minimal risks and side effects. The treatment process usually requires multiple sessions (e.g. monthly or every other month) but this depends on the location of the hair. Your physician will be able to advise you on the number of sessions that is required.

Hair is removed by using laser to penetrate the skin. The heat generated by the laser puts the hair follicle to sleep, hence stunting hair growth. The problem with this treatment process is that the heat has to be there long enough to treat the hair follicles, but not long enough to hurt the surface of the skin (which contains melanin pigment). To prevent this from happening, clinics usually use special sprays to help protect the surface of the skin. These sprays come immediately after the laser bursts.

If you have made up your mind to go ahead with the treatment, make sure you find out from your technician the necessary preparations you should make before and after the treatment. For example, you shouldn't participate in any other forms of treatments (like waxing) 6 weeks before treatment. After treatment, you must also take extra care to avoid the sun. If you must go under the sun, use a sun block to protect the affected area.

It is common for the treatment area to experience a little swelling after treatment. In most cases, the swelling disappears after a few hours. In more severe cases, it may take up to 24 to 48 hours.

During the actual treatment, you may experience slight discomfort during laser bursts. This feeling disappears after a few seconds. The sprays that follow right after the laser bursts may also help to relieve the discomfort.

Most people need between 3 to 5 sessions to remove all the hair. Once the hair has been removed, the area will stay free of hair for a long period of time. After the first session, the hair is noticeably thinned. After the final session, all hair would have been removed.

If you want to keep the area free from hair from now on, you may still need to go for treatment sessions regularly - e.g. once a year or so. Over time, a little bit of hair will still grow back. The additional sessions will help keep the hair from growing back.
