Permanent Hair Removal
The methods that remove hair permanently are: Short-Wave Dia-Thermy and Electrolysis and of late the use of Laser. The first two destroy the hair root and surrounding cells so that no hair can grow at the particular spot again.
Short-Wave Dia-Thermy destroys the root by means of heat. Electrolysis destroys it with a chemical reaction produced by a galvanic current. Coarser hair may need several treatments until they disappear altogether.
Both these methods require extremely fine needles to be introduced into each hair follicle - a process that requires specialised training since the operator needs a highly developed sense of touch and considerable skill in order to judge the requirements of each follicle. Many people find it the best solution for facial hair.
