All three methods (galvanic, thermolysis, and blend) have their own merits, and one method is not better than another. The success depends on the skill of the<unk> st, the type of hair being removed, the condition of the skin and the pain threshold of the client. All three methods, when properly performed, can be thorough at destroying the hair matrix cells, and leaving follicles incapable of regrowing hair. Galvanic method This method is named after Luigi Galvani and uses a person's body as an electrolytic cell. Galvanic electrolysis was first reported in medical literature in 1875 by ophthalmologist Charles Michel as a method for removing ingrown eyelashes. A galvanic hair remover is essentially a positive ground power supply that delivers 0-3 milliamperes through the body. The follicular probe is the cathode of an electrolytic cell. Sodium hydroxide formed at the cathode by the process of chemical electrolysis kills the hair matrix cells. Modern galvanic hair removers automatically adjust the voltage to maintain constant current. Thermolysis Another method is known as thermolysis, also called radio frequency (RF), shortwave or diathermy. Thermolysis was developed in the 1920s and first reported in medical literature by Henri Bordier. A thermolytic hair remover is essentially a radio transmitter, usually with an output of about 0-8 watts at a frequency of 13.56 . RF energy emanates from the probe tip to tissue within about a millimeter. Thermolysis works by heating the hair matrix cells to about , causing electrocoagulation. Blend method The galvanic method and thermolysis are often combined in the blend method, developed by Arthur Hinkel in 1948, which uses both RF and direct current, combining many of the advantages of both methods.
