So, if you have electrolysis done on your chin, any hairs which appear within the next 5-6 weeks are untreated hairs. Also, hormonal changes may stimulate new hair growth. Needle electrolysis requires a series of treatments over time. For example, clearing the hair from a forearm takes a series of fifteen to sixty minutes appointments once a week for about one year. In the first two months, a series of eight treatments will clear of both forearms, but after that, hair on a different cycle of growth must be removed.
Success depends on the skill of the electrologist.
Tweezers epilators, like needle epilators, use electric current to remove hair. Tweezers are used to grasp the hair shaft close to the skin, and an applied electric current travels down the hair shaft to the root. Like needle epilators, an electric shock is possible if the tweezers touch the skin instead of the hair shaft. Tweezers epilator manufacturers must submit to data to the US FDA showing their devices are effective. Tweezers epilator manufacturers can claim permanent hair removal if they can provide supporting data.
