Electrology is the practice of electrical hair removal to permanently remove human hair from the body. Electrolysis is the actual process of removing hair using electricity. In electrolysis, a qualified professional called an electrologist slides a hair-thin, solid metal probe into each hair follicle without puncturing the skin. Electricity is delivered to the follicle through the probe, which causes localized damage to the areas that generate hairs, either through the formation of causticsodium hydroxide, overheating, or both.
Methods
Three methods are used in electrology: Galvanic, thermolysis, and blend. All three methods 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.
Another method is known as thermolysis, also called radio frequency, 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.
Technique
The practitioner selects a metal probe that slides easily into the hair follicle, usually the same diameter as the hair shaft or smaller. The probe is typically 50 to 150 µm for all three modalities. Care is needed to insert the probe at the same angle as the hair is growing out of the skin. The probe is inserted to the depth of the hair matrix, the site where hair is formed. The power and duration of the electricity are started at the lowest setting, then gradually increased until the hair comes out as easily as possible. If the patient experiences significant discomfort, the settings can be lowered.
Treatment duration
Most practitioners will advise that complete removal of male pattern facial hair takes between 1 and 4 years, with an average treatment length of 2 years in case of one session per week, one hour per session. Removal of body hair works considerably faster.
Status of profession
In the United States, electrolysis is regulated in many states, requiring training and licensing. Electrolysis as a profession faced new competition in the 1990s after laser hair removal was developed and promoted as a quicker and easier way to remove hair. However, the U.S. Food and Drug Administration declared laser can only claim to reduce hair growth, not permanently remove it.
