Stick to dermaroller. Dermastamp is totally diff subject.
When I was applying liquid, I applyied 1.4 ml once a day. Now with foam its difficult to messure but one tub is enough for me for 6 weeks. I apply small piches all over head. As you can see in youtube video I made in past.
How about waiting for 30 min before applying?
That's goof to know bc I only apply to the front of my scalp and my last bottle lasted about 7 weeks (twice a day application though)
This Sunday I'll wait 30 mins to an hour after rolling to apply minoxidil. Do you think it's ok to roll with slightly damp hair after shower?
