Today I finally got a 3 months supply of the 5% Rogaine and am eager to start using it but the thing is, most if not all of my hair loss is in my temple and hairline regions. And its pretty aggressive too. On the box it says that Rogaine is meant to be used on the crown area. Does that mean it wont work at all on the hair line? Is it basically a waste of time to try or is there a chance that it might actually do something?
