How Electrolysis Works
During the process of electrolysis, a hair-thin probe that resembles a tiny flexible needle, is inserted into the hair follicle and a strong electrical current is applied, killing the root of the hair. The current is so strong that not only is the hair root destroyed but so is the follicle itself, rendering it permanently unable to grow any more hair. This process should only be accomplished by professional technicians because if the person performing the electrolysis is not competent and well trained it is possible that long-term skin damage could occur, especially in areas where there is a lot of hair to be removed.
Hair Follicles and Hair Removal
Because hair follicles produce hair at different times it is possible that the complete hair removal process may take several visits before the process is finished. When the hair is treated there will always be certain follicles that are lying dormant at that time and those are typically not treated during that particular session, so those follicles will likely grow hair before the next session occurs. The hair follicles that have been treated, however, are permanently destroyed and will not re-grow hair. If hair does grow back it means that the process was never completed in the first place and the treatment was shoddily done.
Home electrolysis systems are quite popular, especially for treating small areas of the body or face, but the only problem with these portable systems is that the electrical current they produce is not as strong as the professional systems and the hair follicles are less likely to be completely and permanently destroyed. Plus, when the person is treating the hair on the face, the use of a mirror is required which can cause distortion in the field of vision, thereby creating problems regarding the correct positioning of the probe.
