I and others have been regrowing our scalp hair by removing our body and face hair from the follicles. I believe we are getting the needed nutrients to grow hair flowing to the scalp follicles instead of being wasted on unwanted hair.
I believe that it is a deficiency of 5 a-reductase that is responsible for AGA. and a poor circulation that causes the pattern in male baldness. Females do not have the severe balding at the crown and temples as males because they do not have the amount of body face hair growth. Ernie
