I love all types of hair. From 1a to 4b(or 4c). 4b hair holds twist so well. Parts of my hair wont hold twist for their life. So i get fed up and end up taking them down. The hair is awesome. NOBODY but us have 4b hair naturally. We're the only ones.
I don't have 4b hair, but still. It's pretty amazing to see how small a curl can get.
