Thanks for the reply. I haven't upped the dosage. I used Folligen after applying minoxidil, so maybe I got more systemic absorbtion, because with the 2 topicals together my scalp was wet. But migraines started when I was using just minoxidil. Sure a day of stress and/or lack of sleep was the reason, but before I was using minoxidil I was in the same situations and didn't get migraines. So I guess it isn't the main reason, but it contributes.
Should I consider stop using minoxidil? Or it isn't that serious?
