  Electrology - Wikipedia, the free encyclopedia
Thermolysis was developed in the 1920s and first reported in medical literature by Henri Bordier.
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.
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.

Thermolysis was first put into practice in 1923, but did not become popular until the 1940s.
All thermolysis equipment operates at a specific radio frequency approved by the FCC (Federal Communications Commission), since it is a type of radio device.
With thermolysis treatment, high frequency radio energy is emitted (mostly) from the tip of the electrolysis needle, first inserted into the hair follicle.

 T~80 Epilator ~ Tutorial - Hi-res
Thermolysis is a method of hair removal by means of heat applied to the follicle and surrounding tissue.
If the thermolysis energy level is too high, the hair may epilate more quickly but a high level of thermolysis dries out the follicle, leaving little to be converted into lye, and when this happens, you will be epilating by thermolysis, even if you think you are using the blend method.
If the thermolysis level is too low, then the client may notice increased discomfort because the insertion times will be excessive and the thermolysis energy is contributing very little to the overall treatment.

 Technical Program
Thermolysis is conducted by heating the powder of precursor gold complexes, as a result the decomposition can proceed in the absence of organic solvent.
These results support that thermolysis of gold(I) thiolate complexes causes reductive elimination of the thiolate ligand to reduce gold(I) to metallic gold(0) and to afford disulfide, accompanying the protection of gold nanoparticles with alkyl groups derived from the quarternary ammonium cation of the precursor complex.
Particle size distributions of gold nanoparticles prepared by the thermolysis of those precursors at 180 °C for 8 h, respectively are strongly reflected by the difference of the alkyl chains on the benzene rings.

The histologic changes induced by thermolysis of hairs of the scalp and legs were studied by light microscopy.
Two techniques were compared on opposite sides: conventional thermolysis (erroneously termed electrolysis) using bare needles and a newly designed precision epilator using an insulated, bulbous-tipped probe.
Thermolysis generally did not immediately eliminate the papilla and hair matrix.

Thermolysis was devised and described as a hair removal technique by Dr. Bordier of Paris, France.
I don't want to be accused of saying that thermolysis is not permanent, but don't worry, someone will do that for me. To further understand the nature of why thermolysis seems at the outset to not kill hair, we must go under the skin, to see how a philo-sebaceous unit works.

Thermolysis allowed for much speedier treatments in each follicle and did not seem to be as painful as Galvanic Electrolysis.
In spite of the speed at which clinicians could work using Thermolysis, electrologists were slow to accept the method in the 1920s and 30s because the machinery for creating high-frequency current was crude and cumbersome for use in hair removal.
It was not until the 1940s that equipment became commercially available and thermolysis became a popular method of hair removal.

Thermolysis is a similar hair removal process that works by inserting a probe into a hair follicle.
Combining the heating element of thermolysis with the molecular transformation produced from electrolysis creates heated lye and it's the heated lye that expedites the follicle base damage.
Because these procedures involve the use of needles or probes, it's of utmost importance that properly sterilized equipment is used to reduce the risk of infection.

Thermolysis of suitable polymers is a comparatively recent process for the production of new types of non-oxide ceramic materials based on silicon, boron, carbon and nitrogen.
Contrary to classical powder technology and sintering, precursor thermolysis offers the opportunity to synthesise predominantly covalently bonded ceramics at relatively low temperatures and, notably, without using oxide additives which are known to lead to ionically bonded micro constituents and deteriorate the mechanical properties and oxidation resistance of such materials at high temperatures.
Another focus of the ongoing research activities are investigations of the mechanisms of the condensation reactions during thermolysis and their structural features.

 Susan's Place Transgender Resources for Transsexuals and Crossdressers: Library: Electrolysis
The most common method practiced today is a form of RF Thermolysis known as FLASH Thermolysis and is popular due to the fact that its speed (in a "flash") of destroying the hair "germ" cells enables more hair to be removed per session, thus making it the most cost-effective method.
The other method of thermolysis is "slow" thermolysis and may be administered by automatic timer or manual controlled duration of a relatively low intensity voltage (usually 10 to 40 VRMS) for from 1 to 3 seconds with the higher intensity settings and from 5 to as much as 20 seconds using lower intensities.
It is also often necessary, due to the amount of lye left in the skin after treatment with the blend method, to neutralize that lye in order to prevent any long term damage to the skin and discomfort after the session.
