Dermaroller Gets Jammed As Does Not Roll Atall

[NAVI]

My dermaroller is getting jammed as I roll it in the hairline ? Why it becomes jammed and stuck and not roll smoothly?

When my hair grows long mine pulls the hair out, so then I have to wait months till those hairs grow back!

So when my hairs short the roller is perfect, I now use an adjustable derma stamp instead when my grows long. So invest in both as they have advantages over each other when the hair is long/short.
