100% permanent hair removal can only be achieved through the treatment of electrolysis, regardless of skin/hair type and color.  First conceived in 1875, Dr. Charles Michel (Ophthalmologist), successfully achieved permanent removal of inverted  eyelashes with the insertion of a solid probe into the follicle and  applying an electric current to render the follicle incapable of ever again producing a hair.  In addition to electrolysis being the only option for permanent hair removal, it has also been proven to be clinically safe.
