WebElectrolysis is a hair removal treatment. A trained electrologist inserts a thin wire into the hair follicle under the surface of the skin. An electric current moves down the wire to the bottom of the follicle, destroying the hair root. The follicle damage prevents hair from growing and causes the existing hair to fall out.
