It likely doesn't have a permanent change in the scalp, which means it is super relevant to put minoxidil right after.
Looks like you are defeating your own argument here?
I am doing light penning every other day to help absorption as well during the healing process, because I believe the scalp closes up quickly. So I don't change my minoxidil regimen, just more penning = more absorption, and the sooner the better so scalp is still wide open in my opinion.
Im not, you are validating it if anything. Again, if there is no permanent change on the scalp, then what difference does it make to put minoxidil right after, assuming you only do the dermapening at the standard rate of monthly of bi weekly sessions. It's just one day of increased minoxidil absorption. How relevant could that be?
