So I am thinking I have a 2b underneath and 2a on top. I can NEVER get the top layer of my hair to wave or curl like the bottom, even with products. I've tried cutting layers, it helps with appearance, but doesn't help make it naturally wavy. Any suggestions? I wash my hair maybe once every three or four days with Organix and I use hair milk to style it sometimes, but mostly I just let it go naturally.

This is my top layer after I sprayed it with some leave in conditioner and tousled it around. It is usually frizzy and straight with slight body

I flipped my hair over to take this photo, I typically do not apply anything directly to this part of my hair - it's just naturally like that. My hair is very VERY thick also.

Anyway, how can I get the top layer to look the same Sorry for the long winded post!
