Lightsheer laser hair removal can be used to remove unwanted body hair from any region because the energy level of the laser is low. During laser hair removal, the laser passes over the affected area of the patient's skin. The laser energy targets the pigment of the hair follicle and shaft. The heat from this light damages the follicle of the hair and in a brief amount of time, the hair that once grew from the damaged follicle will fall out. This can take up to two weeks. This procedure is most effective on hair in it's growth state. Light coloured and white hair are resistant to this treatment because of their lack of pigment. Laser hair removal requires a series of 2 to 5 treatments spaced 4 to 6 weeks apart. The number of treatments and time varies by patient and the area treated. It takes the most time to treat large areas with dense or thick hair. Like any laser surgery or procedure, laser hair removal may require some recovery time. Patients usually experience some mild redness, tenderness, and swelling of the treated area. Patients are advised to avoid exposing the treated area to the sun following laser hair removal, but can return to daily activities immediately after the procedure.
