I have 2c/3a hair. Normally the front is pretty curly but there is this one area in the back that will. not. curl.
I tried scrunching, diffusing, long layers, adjusting the amount of product, etc, but I always wind up with that one spot right at the back of my head that isn't curly.

Anyone have any suggestions to fix this, or ways to make the back of your head curlier in general?

I dont know if you can see it in these pics but its right there smack in the middle of the back of my scalp.
