Question about Rogaine Foam

[JMay83]

Hey everyone. I'm 25 years old, and just noticed a few months ago that I had started thinning out on the crown of my head. I decided to use Rogaine Foam, but for some reason decided to use the foam on the entire top of my scalp, including the front. To say the least, it really thinned out my hairline, and thus, after a week or so of using the foam on the front of my scalp, I continued only using it for the crown area of my head. My question is; will this hair grow back on the front, and mid section of my scalp? It honestly really has bothered me, though conventional wisdom would tell me that I should grow back the hair I shed after beginning the foam. I'm continuing using the foam for the crown of my hair, as well as started taking Propecia. Hair loss runs in my family, so I figured I'd be proactive, and that at the first sign of hair loss, I'd start fighting back. Thanks!
