Humidity question for hair?

Question

soo, my hair is naturally curly/thick. but i like it better straight, so i straighten it majority of the time. it's been raining alot here, which is increasing the humidity very fast. if my hair is COMPLETELY straight before i leave the house, by the time i walk outside, my hair starts to frizz and poof and curl. i tried using tresemme humidity hairspray after i'm done, but it doesn't help one bit. i need suggestions. i'll appreciate it.
