Has anyone used Aminexil without minoxidil or any thoughts about it? Aminexil is a more recent discovery that has been used commonly in shampoos for hair loss prevention. It has been found to prevent the hardening of the hair shaft and collagen buildup around it. A lot of the products are for women. Doesn't mean it won't help out guys. Derma rolling is centered around getting rid of the collagen. Roller + Aminexil =????
