Are there any studies to show how much minoxidil goes systemic when dermarolling? i know the average is around 5mg when not dermarolling, i was rolling and experienced side effects like bloated face etc Im wondering if i could just apply without dermarolling and not experience side effects, i stopped in april and my hair is a mess. I think minoxodil thinned my hair a bit aswell, i used to be able to comb over the right side of my crown and not see any scalp before finasteride and minoxidil, now when i do it scalp is showing.
