YES! its basically dht.
I found that 4 - 5 grams of b-5 (panthotenic acid) seems to limit/reduce the oiliness as well as the hair loss from the proviron (as well any androgenic aas).
if you are hair-sensitive, you'll actually feel "pain" in ur scalp within a few days. if you stop right away, you should be ok.
1st time i did a few weeks of 50 mg proviron without b-5 was a killer on my hair. worse than any cycle i did. slowly got it back with minoxidil.
