Thicker Hair Doesn't Curl
I have thick 4a type hair.  It was a chore to hold the barrel upside down (felt awkward).  I had it on the highest heat and it wouldn't create a curl pattern.  It hardly waved my hair at all.  Maybe it's good for fine or thin hair, but mines not so much.  I'm returning to get a regular, barrel type curler.
