I think I have really think skin. I use 2.0 on my face and scalp and rarely do I ever get any bleeding. I started to push real hard also and still no blood so now I think I should graduate to the next one. ever after needling with the 2 I feel I could roll again a week later my scalp feels fine. I never use minoxidol on same day but I think I should im lookin for a little bit more regrowth in my crown then I would be happy. Any one else use bigger needles? I also order the 1.5 mm so I can roll and put minoxidil on right away.
