My crown area is my weakest spot. I was on the birth control patch for 3 months and then stopped. Right now I have loss scalp hair at the crown (almost bald). I never wear ponytails. I don't know if this is from the birth control or from stopping the birth control. Do you ladies have any suggestions. Currently I use Mizani products. I just started vits- One a day womens, Biotin 1000mcg, B-Complex.
