Modalities
Three methods or "modalities" are used in electrology. Galvanic, thermolysis, and blend all have their own merits, and one method is not better than another. The success depends on the skill of the electrologist, 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
This modality is named after Luigi Galvani and uses a person's body as an electrolytic cell. Galvanic electrolysis was first reported in the medical literature by ophthalmologist Charles Michel in 1875 to remove ingrown eyelashes in patients with trichiasis. A galvanic epilator 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 epilators automatically adjust the voltage to maintain constant current.
Thermolysis
Another method is known as thermolysis, RF, shortwave or diathermy. Thermolysis was developed in the 1920s and first reported in medical literature by Henri Bordier. A thermolytic epilator is essentially a radio transmitter, usually with an output of about 0-8 watts at a frequency of 13.56 MHz. RF energy emanates from the probe tip to tissue within about a millimeter. Thermolysis works by heating the hair matrix cells to about 48°C (118°F), causing electrocoagulation.
