I would try to move the pen in a tapping motion and not just slide it across the scalb. While you are moving some of the needles could still be in the skin and then you would drag dem further and "rip" the skin more

Did you know that alot of men comb their hair after a shower when it's still wet? Women don't even do that. Men don't realise that years of combing hair straight after a shower while still wet is like pulling at your hair at it's weakest. Towel drying is not enough. Blow drying or letting it air dry before combing is what you need to do to stop balding.
