I used rogain twice a day for only three days and now a month later i still have dark circles, unfirm skin and fine fines on my forehead. My forehead feels dry, stiff, numb, and sometimes burns. My forehead came into contact with the minoxidil via a knit cap and pillow. I am seeking advice in terms of recovery time. Is this numb sensation i am experiencing on my forehead from collagen being produced in the inflammed forehead area? I was a very young looking 32 year old without any issues before i used rogaine.
