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 with the Na+ ions to form NaOH (Lye). The highly alkaline nature of the lye destroys the germinal layers of the hairs present at the hair root and prevents the regrowth of the hairs.
The chemical reaction that occurs is
|2 NaCl(aq) + 2 H2O(l)
||2 Na+(aq) + 2 OH-(aq) + H2(g) + Cl2(g)|
The hairs are permanently removed. The disadvantage is that it is time consuming as it may require 2 to 5 minutes for the complete electrolysis cycle to complete.
The process of electrolysis was first used for permanent hair removal in 1875 by Charles E. Michel, M.D. who used it to remove ingrown eyelashes in patients with trichiasis.
Since it is the sodium hydroxide, or lye, which is the source of follicle destruction in the galvanic method. The galvanic method is basically a chemical process.
With the galvanic method, the body salts combined with the moisture found in body tissue make a type of salt water solution. The moisture content of this salt water solution is at its greatest concentration deep within the follicle. When the electrolysis current is applied to be inserted needle, the newly manufactured lye causes a chemical decomposition of the hair growing cells to occur. Two electrodes are required for this process to take place. One electrode is the electrology needle, the other electrode touches the patient's body in some location. This "patient electrode" is usually a metal wand held in the patient's hand. The galvanic method kills about 80 percent of the hairs treated.
