Hairs falling out is a androgen DHT issue. You might want to also add all the DHT blockers topically.
I take 4 ml 5% generic minoxidil, mix it with 100mg spironolactone, 62.5mg Flutamide, 0.125 dutasteride, 2.5 finastride and apply twice a day. That way your applying them directly to scalp to affect hair...
