Once again, I did some reading to help our cause. Turns out that follicles are located approx. 1.5 to 2 mm below scalp surface. So if you reliably wanna induce wounds there, you actually would have to get a 1.5mm dermaroller. Anyone brave enough for a 1.5mm one?
Well, that's exactly what the study says, 1.5 mm. So you'll have to bite the bullet and go for it.
