I dunno. I feel the other way, we have good anti-androgens, admittedly with a chance of sides, we just don't have good enough growth stimulants to re-awaken our miniturised follicles.
But yeah minoxidil is the best we have so far and I don't trust those random brands claiming high percentage minoxidil, I'm sticking with the reputable stuff = Rogaine/Kirkland/Spectral.
