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. Private costs vary and are usually based between £1 - £2 per minute of treatment so range from around £60 - £120 per hour. It is impossible to give a estimate on clearance of an area as hair growth depends on hormonal and other factors but for complete permanent removal each hair has to be treated a number of times whilst it in the growing stage.
