Is it normal? Also... How often should i use the 1.5mm on my scalp? Once a week? Month? And am I supposed to roll till my scalp draw few drop of blood?
Another quick question, I've read/watched videos that when use 1.5mm your scalp turns red like cooked lobster.... But when I used mine.. my scalp doesn't turn red.. am i doing it right? I'm asian with fair skin btw, not sure if it helps. Though all of the videos i watched were Caucasians..after dermarolled their scalp turn red.
