A. The truth is, there is no 100 per cent guaranteed permanent hair removal method. However, there are certain options that are considered to be better than others with regard to permanency. One hair removal method that can be considered permanent is electrolysis. The procedure requires burning the hair follicles and damaging them so much that your body is unable to repair them. With the follicles damaged, they cannot sprout new hair. But, it does not last forever. People who undergo this type of hair removal end up re-growing body hair after a few years. After about 10 years have passed since the completion of electrolysis, hair follicles have been found to have re-grown at least a percentage of body hair. It may not be as dark or thick as it was before the electrolysis, but it's still visible.
