Propecia question, for once not about ED or sex side effects!

[Cr779]

Well I've finally accepted that I am in fact balding and that my hairline is receding. I'm 20 and if not a NW2 will be one soon since I've seen the hairline recede at least 2 cm on my left side in a matter of 3 months. I've been going crazy over the whole propecia question as I've always been very, very wary of drugs to solve any problem. But anyways to cut to the chase I've heard people say that after 5 or 10 years your body starts to get used to propecia and your hair loss will continue again and that how long it takes for your body to grow immune varies from person to person. Can anybody shed any light onto this for me, since if this will only keep my hair for 5 or 10 years(so till im 25 - 30) id rather not start taking this since if I'm gonna go bald 5 years down the road i may as well just get used to it now instead of buying some time then going through this horrible realization and depression over hair loss again.
