I got rid of the dark hairs on my face, now left with white quills. Problem is that the hair/ hair follicle is in one of three stages in a 18 month to 24 month period. So if it is actively growing, you can pull it, or fry it. If it is in a rest stage, then you will can pull the hair but the root remains intact, and dormant stage,where there is no hair but the root will reactivate in its own time. You clear one cycle, and the next replaces it. So two years of electrolysis minimum assuming that you can clear all the hair at one sitting.
