Here is what Michael was getting at. Shaving, does nothing to the hair. It simply cuts the hair off at the surface. It does nothing tot he follicle . You did nothing wrong, the hair you have growing is simbly because of your age and the hormones active in your endocrine system. There is absolutely no way you could have shaved and affected the hair follicles in ANY WAY.
Electrolysis done properly disables the hair follicle and that follicle never grows another hair. So it is permanent. Your skin has a set number of follicles and once disabled they never grow another hair ever.
Some follicles previously dormant may develop a hair if hormone changes dictate it, but once disabled they too never grow another hair.
So relax. Electrolysis works and is permanent.You may want to consider though if they are fine hairs whether they are worth removing with electrolysis . Shaving may suffice.
