Galvanic, Thermolysis Blend Methods
The modern electrolysis epilator uses the time-tested method of electrolysis. These hair removal systems are basically still the same as the first galvanic hair removal epilator built in 1875!
An electrolysis epilator is used to destroy one hair follicle
at a time.
The treatment is quite expensive, because it is very time-intensive.
The three modern methods are galvanic, thermolysis and a blend
of the two methods.
The galvanic and thermolysis methods both have its own strong and weak points. By blending the two methods, the best of both are used, while the negatives are lessened.

How does an electrolysis epilator work?
Galvanic electrolytic cells (a battery) are used as power source with an anode (-) and cathode(+) to form a direct current inside the electrolysis epilator.
Direct current always takes the shortest route possible. When direct current is applied to a water and salt solution, a chemical process is the result.
Sodium hydroxide (lye), hydrogen gas, and chlorine gas are formed. This process is called electrolysis.
This process was first reported in medical literature in 1875 when opthalmologist Charles Michel used it to remove ingrown eyelashes in patients.
Galvanic electrolysis hair removal
Water and tissue salts are naturally present in the human body. Their concentration is highest deep inside the hair follicle. The battery is the electrolysis-epilator, the cathode is the probe and the anode is normally a wand held in the client’s hand.
When the direct current is applied from the electrolytic cell, or the electrolysis epilator, to the probe inserted in the follicle, caustic lye is formed in the follicle during the chemical process.
This causes a softening of the surrounding tissue and chemical decomposition (dissolving) of the dermal papilla and tiny blood capillaries that supplies nourishment to it. The result is permanent elimination of the regenerative ability of about 80% of the treated hair follicles.

Why is the process called galvanic?
The process was named after Luigi Galvani. Due to the slowness of this process, the single needle galvanic system is no longer used as electrolysis epilator.
However, modern electronic design allows the multiple needle galvanic method (12 to 16 hair treated simultaneously) to work very effectively.
It comes as no surprise that this electrolysis method is also called: sodium electrolysis, salt electrolysis, current electrolysis and chemistry electrolysis.
Because lye is a fluid, it is very effective to destroy distorted follicles. A probe has difficulty reaching the correct spot when the follicle is distorted.
Thermolysis electrolysis hair removal
The method was developed in the 1920s because the galvanic method was too slow. Dr Bordier of Paris, France, first introduced it as a hair removal method in 1923. Henri Bordier was the first who reported this method in medical literature.
Thermolysis only became popular amongst electrologists during the 1940s. The electrolysis epilator uses an oscillating, high frequency current and is also known as RF, shortwave or diathermy.
The electrolysis epilator is used as a radio transmitter to produce high frequency energy when the current move back and forth extremely quickly to produce enough heat to electro-coagulate the dermal papilla. It operates at a specific radio frequency approved by the FCC (Federal Communications Commission).
This method is exceptionally fast and very effective for fine, thin, straight hair with shallow follicles, but not very effective for the destruction of coarser hair. This lead to the development of the electrolysis blend method.
Galvanic and thermolysis blend
The blend or dual method was patented in 1945 by Henri St Pierre and Arthur Hinkel. Both the galvanic and thermolysis methods have their limitations. The blend method maximizes the advantages, and minimizes the shortcomings, of both methods.
This technique is based on the theory that lye is more caustic when it is heated. The heat makes the tissue surrounding the dermal papilla more porous, and easier for the lye to diffuse into it.
By combining the two methods into the same electrolysis epilator, the chemical reaction occurred quicker in galvanic at higher temperatures. The dermal papilla, as well as the tiny blood vessels that supply nourishment to the follicle, are dissolved by the hot caustic lye.
The blend method is very successful with coarse, curly hair or distorted hair follicles. Very good results are achieved with beard removal of transgender clients.
