From Wikipedia, the free encyclopedia
- This article is about the method of epilation. For
the chemical process, see
Electrolysis.
Electrology is the practice of electrical
epilation to permanently remove human
hair.
An electrologist is sometimes referred to as an
electrolysist in the
United Kingdom. The actual process of removing the hair is
referred to as electrolysis. The practitioner slides a
hair-thin metal probe into each
hair follicle. Proper insertion does not puncture 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 caustic
lye (galvanic method) or by
overheating (thermolysis method).

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.
[1] 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.
[2] 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,
causing
electrocoagulation.
Blend
Galvanic and thermolysis are often combined in a method known
as blend, developed by
Arthur Hinkel in 1948, which uses both RF and direct
current, combining many of the advantages of galvanic and
thermolysis.
[3] All three of these
methods use a metal probe 50 to 150 µm (0.002 to 0.006 inches)
in diameter which is inserted into the
hair follicle to the depth of the dermal
papilla or hair matrix, which is the site of formation of
hair from highly
mitotic and
keratinized
cells.
Status of profession
In the United States, electrolysis is regulated in many
states, requiring training and licensure.
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 permanently. However, electrolysis
regained lost popularity after the
Food and Drug Administration declared laser and similar
devices can only claim to reduce hair growth, not permanently
remove it.
