Hair begins to grow in an area with a major follicle producing a coarse hair, surrounded by finer follicles that may or may not be producing hair at this time. It will often seem, after some electrolysis treatment, that the treated hair is regrowing somewhat finer. But here's what's really happening. The treated hair has been permanently removed. However, since we treat an effect (hirsutism), not a cause (androgen production), a finer follicle adjacent to the treated hair may now be stimulated by the existing androgens to produce a hair. It is finer since it grows from a finer follicle. The hair that seem to appear as regrowth often is in reality additional adjacent hair now beginning to grow. This is the reason it takes time to accomplish permanent removal of all the hair, the ones that are visible and growing and also those that have the potential to grow. When a hair is treated properly by electrolysis, it is removed PERMANENTLY and can never return.
With a series of regular treatments, all the hair follicles that are stimulated to produce hair in an area will be treated and the area should become hair free. It is very important to note that a series of REGULAR treatments will accomplish better total results in a shorter overall period of time.
