Electrology is medically recognized as the ONLY method of permanent hair removal. Unwanted hair is removed by placing a sterile needle/probe into the hair follicle and transmitting a small amount of electrical energy into the follicle. The current destroys the hair's regenerative cells, and the treated hair is then removed from the skin. Once the regenerative cells have been eliminated, there is no possible way for each individual hair to be reproduced. Electrolysis is the perfect treatment for those few stubborn hairs, regardless of color. It is not an appropriate treatment for large areas.
