Laser hair removal and Electrolysis are the two technologies that offer you lasting reduction in hair growth. Electrolysis uses electrical energy to create a thermal and chemical injury to mature hair follicles. When done professionally, this can result in lasting hair growth reduction. The problem is that only mature (larger) hair follicles can be treated, the process is tedious and there is some potential for damage to the skin surface that may cause scarring. This is often impractical for anything other than small areas. You can count on many sessions (>10) to see a worthwhile impact on commonly treated areas. For very small zones, light colored hair, sparsely located coarse hairs on delicate areas or hairs associated with moles that are not going to be removed, electrolysis is still a primary strategy.
Laser hair removal (LHR) can effectively disable hair with follicles (hair shafts) of many different sizes. Less damage to the skin surface occurs newer technologies and very careful technique. LHR can also treat small or larger areas very efficiently with most patients achieving lasting reduction after 5-6 sessions. The limitation of LHR is that light colored (blond, grey and red) hair does not respond well. If you think the options through, going to a reputable clinic with current technology is the safest, most efficient and most economical solution for unwanted hair growth.
