I was on Minoxidil for six months and got good filling in pretty nice. With its use on my scalp I saw minor improvement. Two months ago, I started to use Finasteride and noticed my beard became patchy again almost like before I started using the Minoxidil. I want hair and a beard. I am not getting any side effects of either drug.
Finasteride is known to reduce beard and body hair in some people. Minoxidil on the beard may help it regrow. You might consider a higher dose if Minoxidil if you can tolerate it.
