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.

When inserted properly, electricity is delivered to the follicle through the probe which causes localized damage to the areas that generate hairs (either through the formation of caustic sodium hydroxide, the galvanic method, overheating thermolysis — or both the blend method topic modalities).
Three modalities 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 3 methods, when properly performed, can be thorough at destroying the hair matrix cells — thereby leaving follicles incapable of regrowing hair.
This modality 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 Mitchell as a method for removing ingrown eyelashes.
A galvanic hair remover is essentially a positive-ground power supply that delivers 0 to 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 (this kills the hair matrix cells).
Modern Galvanic Hair Removal Demonstration:
Modern galvanic hair removers automatically adjust the voltage to maintain constant current. Topic/ Thermolysis – another method – is known as thermolysis (also called radio frequency), RF short wave, or diathermy. Thermolysis was developed in the 1920s and first reported in medical literature by Henry Bohr.
A Thermalitic Hair Remover is essentially a radio transmitter –usually with an output of about 0 to 8 watts, at a frequency of 6 megahertz. RF energy emanates from the probe tip to tissue within about a millimeter; thermolysis works by heating the hair matrix cells to about 48 to 50 degrees Celsius (118 to 122 degrees Fahrenheit), causing electrical AG.
Topic/ Blend method — the galvanic method and thermolysis are often combined in the blend method (developed by Arthur Hinkle in 1948), which uses both RF and direct current – combining many of the advantages of both methods.
Topic/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 micrometers to inches for all 3 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 at the site where hair is formed. The power and duration of the electricity are started at the lowest setting, then gradually increased (til the hair comes out as easily as possible).
If the patient experiences significant discomfort, the settings can be lowered. Topic treatment duration: most practitioners will advise that complete removal of male-pattern facial hair takes between one and four years with an average treatment length of 2 years.
In case of one session per week & one hour per session, the removal of body hair works considerably faster.
Topic: status of profession in the US — 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 US Food and Drug Administration (FDA ) declared laser can only claim to reduce hair growth. (not permanently remove it )
