Galvanic method or Direct current method - in this technique direct current is applied to the root of the hair. The patient holds the negative electrode while the positive electrode is inserted into the hair follicle. The current when passes through the water and salt (NaCl) in the hair root, it gets dissociated into sodium, hydroxide ions, chlorine and hydrogen.   Electrolysis of aqueous NaCl solutions gives a mixture of hydrogen and chlorine gas and an aqueous sodium hydroxide solution (lye). The water when reactions with electric current produces OH ions. 2H2O(l) + 2e–  ==> H2(g) + 2OH-(aq) which react…

Thermolysis method or Shortwave diathermy method or radio-frequency method - in this technique alternating current is passed through the needle which heats up the needle inserted into the root of the hair. A fine wire probe is used to transmit radio waves to tissues near the probe.Radio Frequency Diathermy (The therapeutic generation of local heat in body tissues by high-frequency electromagnetic currents) or Short Wave Electrolysis.  Molecules within the tissue are caused to vibrate which lead to a rapid increase of the temperature, causing coagulation (to change or be changed from a liquid into a thickened mass: egg white coagulating…

  BLEND METHOD 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. The blend method, also called dual action method, is the combination and simultaneous use of galvanic and thermolysis techniques. This combination method alleviates the shortcomings of each of the individual techniques, while bolstering their advantages. By doing so, blend electrolysis incorporates the high kill rate associated with the galvanic method along with the swiftness found in thermolysis. It is especially useful in treating…
