As an mtf using it for head... First, just to reiterate what others said, don't buy Rogaine itself if you don't have to, it is significantly more expensive for the same product. Kirkland is probably the most commonly bought off brand (it's Costco's), and I buy the liquid on Amazon for 20-25 for packs of 6(supposed to be 6 months worth, but mileage varies). That being said, be aware there are two delivery mediums: liquid with eyedropper, and foam. The foam is more expensive, but is generally just all around better and has more consistently effective application. It's difficult to work with the liquid without going overboard and using like three doses at once just to ensure highest coverage. Using it on your face where gravity is a bigger issue, I feel like you might want to shell out the extra money for the foam version as the liquid is really, really hard to keep in place (even on scalp it just runs off my head in all directions). Maybe someone using it for beard can offer their insight on the liquid on face though, maybe it works just fine if done right.
