I am 25, and have been slowly baling for the past 3-4 years. My hair is curly, so for a while it wasn't showing, but this summer I decided to buzz it and I love it. Lately though, the crown has been showing skin and even though I will probably keep it short, I still want to have a full-ish head of short hair. I ordered Rogaine this week and will start using it this weekend, and have been wrestling with taking Propecia for years now; at first I was inclined to pull the trigger, but lately an abundance of sex made me conscious that any possible problems with erections and ED are far worse than a bald head. I read that the working principle of Propecia and Saw Palmetto is similar, and when I took SP I never had problems with ED, so I am hoping that IF I do take Propecia it will be the same case. In any way, good luck with your treatment and it does look like its working. Any tips on maximizing effects of Rogaine and any other application tips?
