How long should I give Propecia?

[nassau]

Hello All,
I started taking Propecia about a month ago and I am wondering when should I expect to see resluts if I am one of the lucky ones who regrew hair. I am 23 and have major thining on the top of my head and also a receding hairline. The only good news is I don't have a bald spot yet and I hope I never will. Hairloss dosen't run in my family really, I have 2 brothers senior to me by 10 plus years and my father is in his 60's and has thining and a recided hair line but he did not acuire that untill he was in his 40's. So I was just wondering how long I should give propecia to work if it is going to thicken up my hair. I was told by the doctor that the hairline would not regrow with propecia but my hair should thicken up. I would just continue to take it, but I think I might be one of those unlucky ones that got those bad side effects. I never have morning errections anymore and I hardly get those random errections that I grew acustom to. So I just wanted to get some input from propecia veterans and what they would suggest.

Thanks in advance
