Electrolysis has become a widely available treatment in many beauty salons for the permanent removal of unwanted hair for both men and women. Electrolysis is the removal of unwanted hair through the means of a probe or needle inserted into the hair follicle. There are three different methods available on the market, Galvanic electrolysis, Thermolysis/Diathermy/Short Wave Electrolysis and Blend Electrolysis. The aim of all the methods is to damage the base of the growing hair in order to cut off the blood supply and nutrition to the hair, preventing any new growth from developing. The technique when performed correctly is highly selective and no damage should occur to surrounding tissues.
