I used Retin-A on my face and didn’t get more hair growth. If it were known to increase hair growth men would be rubbing the stuff into their scalps daily.I suspect you were paying more attention to your shaft skin and the hairs growing from it than usual.
It’s quite possible that I was paying more attention to my shaft hair than usual, but there was a definite increase in the number of hairs. I’m talking about 10-11 little small hairs, spaced out. I was just stating that it was one possible side-effect of retin A, just like vommiting, diarehea, uncontrollable bowel movements, weight gain are some side effects of asprin (ok maybe not, but you get my point). I didn’t mean that the hair growth would be significant enough that your penis would look like big foot. Plus I doubt men with reseeding hair lines could even get their hands on that stuff, if only for hair growth, or would want it, for it’s lack of strength.
