Electrolysis is a method of removing individual hairs from the face or body. Today's medical electrolysis devices destroy the growth center of the hair with chemical or heat energy. After a very fine probe is inserted into the hair follicle, the hair is removed with tweezers. Most areas of the body can be treated with electrolysis, including the eyebrows, face, abdomen, thighs, breasts and legs. There are generally no permanent side effects, but sometimes a temporary, slight reddening of the skin may occur. Many factors influence hair growth, so you will need to return for several electrolysis visits. The total number of sessions needed to remove hair permanently from a particular area will vary from person to person. Most clients return once a week or every other week as needed, but the unwanted hair will be gone forever once the series of treatments is complete. Each treatment lasts between 15 minutes and 45 minutes.
