Electrolysis is a method of hair removal that uses fine needles to apply electric current to the hair root. In simple words the technique burns the hair root preventing further hair growth. Electrolysis hair removal is therefore a permanent solution for unwanted hair. The FDA has approved only electrolysis as the permanent hair removal method.
Electrolysis for hair removal is of three types
In this procedure the AC current is passed through needles. This causes the water molecules around the hair follicle to vibrate. The vibration causes heat which in turn damages the hair follicle. This method of electrolysis is faster than the others but also less reliable.
In this procedure a DC current is passed through the needle which causes the hair follicle to produce lye (sodium hydroxide). This chemical destroys the hair follicle and prevents hair growth.
The method is a combination of thermolysis and galvanic forms of electrolysis. Here both AC and DC voltages are applied simultaneously through the needles. It is a quicker method as compared to galvanic electrolysis.
Electrolysis gives the best results among all other hair removal treatments. The effects are very often permanent and are the only known solution for getting rid of hair for a long time.
All kinds of hair and skin types can benefit from this method as this treatment does not involve removing hair pigmentation. In fact, in cases where laser treatment is not considered suitable electrolysis is the suggested alternative.
There are some minor cons associated with this technique. Bent hair follicle is one such obstacle which makes the needles difficult to probe through the root of the hair. Further, it is a time consuming process requiring up to 30 sittings spread over a period of 12 to 18 months. Choice of a bad technician can lead to pigmentation of the skin. All said and done, the basic procedure involves removing each hair from its root and hence can be a very uncomfortable for the person undergoing it.
