How can I keep the top layer of my hair frizz-free?

I have mostly 3B hair with some 3A curls, and for the most part, I've managed to keep my hair pretty smooth and moisturised...but the top layers of my hair are really prone to frizz. It didn't bother me too much until I found an area at the back of my head that was so frizzy that I lost all the curls and it was just a straight-ish frizzy mess. Any ideas? Thank-you!

I have the same problem with the back because my hair is not long enough to pineapple, so that part gets mashed when I sleep. I've found that it helps to make a few finger coils in the back when it's damp.
