Any hair products you girls swear by???

Okay, I have super curly, frizzy, textured hair. I can normally tame it in dry weather but I just moved to Florida and I know that on a super humid day it will just poof. I've tried lots and lots of different products and methods but it just doesn't seem to help. Any new ideas or products? I've heard coconut oil is good, what's the method on how to use it for hair (if anyone knows)?
