So, i live in fl & obviously we have high humidity, & lovely rain, but, i cant keep my straightened hair to stay staight. I don't really like using serums because they make my hair oily even when i dont use a lot, & already I have soft hair, so for some reason its more prone to getting curly or poofy when it's relaxed. I was thinking i would need a gel or hairspray that wont turn to mush in our weather, but i've yet to find one that'll work. any suggestions? please & thanks :]

Frizz ease gel works wonders.The spray isn't so hot.
