Regressive phase called the catagen stage which lasts about two weeks, during which the hair stops growing but is not yet shed. Resting phase called Telogen stage which lasts about 5-6 weeks, at the end of which the hair falls out and a new hair begins to form. The method you choose for dealing with unwanted hair will depend on the number and location of hairs and how great a problem you perceive them to be. Temporary methods such as shaving, depilatories and bleaching are popular but not very satisfying. Other methods such as waxing and tweezing last only 20 to 90 days and can cause ingrown hairs and trauma to the skin.
Electrolysis is the only permanent method of hair removal.
This process involves a very fine sterile probe inserted alongside the hair in the hair follicle. A very slight amount of current is applied through this probe, which destroys the hair root, ending further hair growth. The skin is not punctured or harmed in any way, and for most people the entire process is no more uncomfortable than tweezing. A series of treatments is necessary since the hair grows in cycles and at any given time only a percentage of the hair growth is visible above the skin and actively growing. Electrolysis is effective on all colors of hair and can be used to treat any area of the face and body.
