I'm using the liquid minoxidil formula, but basicaly it's the same thing, I can only speak from my experience:
don't panic if you will notice that your hair will fall out like Crazyy-it's part of the process, that's only shedding; itchy scalp; white flakes from the dried minoxidil, dizziness (I had it like 2times, but I'm not 100%sure it was from the minoxidil); and possibly red face after aplying- I had it especially at the beggining.
You don't have to worry so much about the greasy hair, bc the foam doesn't leave such an oily mess on your head after applying.
Basically these are the things you should experience, or at least the things that I've experienced since I've started using Minoxidil about ~2 and a half months ago.
