I've had similar results to yours at the hairline (I have female pattern hair loss too) but that was at 1.5 months of consistent use of minoxidil twice daily, I've been thinking about using a derma roller so I'll get the 0.5 mm one and work my way up to 1 or 1.5 as the famous study, do you apply the rogaine right after dermarolling or do you wait a few hours?
