Does Minoxidil Work On Receding Hairlines?
When Rogaine achieved it's approval as a hair loss product, it's clinical trials only tested it on the crown, not on the hairline. This means the makers of Rogaine cannot claim that it works on the hairline, though many users have proven that it does through real world experience. That's the good news.
The bad news is it doesn't usually work as good on the hairline.
For whatever reason, a receding hairline tends to be much tougher to restore with treatments like Propecia and Minoxidil than the crown, so for most people these drugs will only have a very limited impact on the hairline. For others, however, incredible results are achieved: There simply is no way to determine how well you will respond other than to try it and see.
So, yes, Minoxidil can work on the hairline - as can Propecia - it's just they aren't usually hugely effective in this area for most people. Maybe you'll be lucky?
