Electrolysis hair removal is an effective and safe method of hair removal. It works by sending a tiny electric current through the hair follicle, which destroys the hair root and prevents the regrowth of hair in that particular place. The number of sessions required to achieve lasting hair reduction depends on factors such as skin sensitivity and hair coarseness, hair type, and the area being treated. It can also be used to remove white hair, hair that is not well suited to laser hair removal as well as fine hair on the face or body. A needle is inserted into the follicle and a current is applied, which destroys the cells that produce new hairs. This method can be used on any area of the body, but it is most commonly used on the face, bikini line, and underarms.
