Loosing your hair does suk. When I took the plunge for the first time I had no one to help me out, there were no boards like this one where I could've went to for some information. Use the people on the board and listen to them they have been there and done that several times over. At 21 you take a chance I took one as well at 23, I am just thankfull that my hair loss has'nt gotten any worse, but who knows what will happen 10 years from now. I continue to take rogaine and hope it works, just remember no body but god can forecast someone's hairloss not even the best doc's.
