You should keep using it. I’ve been on the dermastamping + the ZT and it’s doing something for sure. Just not strong enough without an Anti Androgen. How it’s made my eyebrows thicker and darker and filled in my stubble is remarkable. Not what I was looking for but surely this should be doing something in the scalp for the hair??Had no faith in in took a gamble on derma rolling seems to have more proof.hope it works for you
