I just started using the Foam a few days ago, it's the first time I've used minoxidil. I still have quite a bit of hair to the point where it makes it hard to use because it gets all over the rest of my hair. I'm receeding on the right side on the hairline so I'm just trying to use it there to see if I can get back what has receed over the last 2 yrs or so but my worry is since the foam is getting on my hair that i already have, is it possible that if I stop using the foam that the hair I already had could become minoxidil dependant and fall out just like the hair I could regrow using the minoxidil would if I stopped using it? If that is possible I'm going to stop using it immediately.
