The smell is ok (bit like the dough kids play with), I've grown to like it. The only problem I have with it, is the staining, but since I cut my hair back and am now able to rub into scalp, it's not so bad. Anyways, I apply it at night, then wash it off in the morning.
Combining it with minoxidil foam and Nizoral, I've seen noticable results. Baseline photos taken about 2 weeks ago
As far as I understand, apart from spironolactone (the 2% liquid does stink, big time) Revivogen is the main anti DHT topical. Correct me if I'm wrong; still trying to get my head around all the info on this site.
