Hey man, I thought about doing the same thing. While there is some validity to the rogaine experiment, you're way to young to consider it as an option at this point. In my opinion it should be an absolute last ditch effort to attain a beard. Like, if you're in your 30s and have seen no progress from where you are now and are still desperate. And while you're right that most asian men don't have full beards, I have seen plenty of asian men that can rock a goatee or a mustache goatee combo that I think look cool because their hair is nice and dark. The bottom line is: you can't yet tell if your genes have doomed you at 18 years old.
