I don't have any problems about re-growth . I had hair loss and started taking propecia 0,5 mg treatment. And it didn't stop my hair loss. I have been taking it for 3 months.
Propecia takes time dude. I've been on it for two years now and I remember the first few months it didn't look too great. Give it at least six months then speak to a doctor if you think it isn't working.
