Humidity

My hair is somewhat wavy (not enough to be pretty, but enough to be a pain). I use a straightening balm and a hair dryer to make it straight. The problem is that I live in WV and the humidity here in the summer is unbearable. I could be having the best hair day, but that generally changes once I go outside. Once my hair is out in the humidity, it just goes wild on me. It starts flipping up in places and gets a little frizzy. It doesn`t get too frizzy, the flipping up is the main problem. Does anyone know of a product or have any suggestions as to the best way to keep my hair from absorbing the moisture?

Thanks for the advice, but unfortunately that`s where the "not enough to be pretty, but enough to be a pain" thing comes in. I`ve tried to style it to enhance the waves, but it just ends up looking like a disaster. :( On the up side, I`ve been letting it grow out so at least it`s long enough to pull up when I want to. I just don`t like doing that very often.

I live in MS, where the humidity is intolerable. I have found much success with John Freida`s Frizz Ease extra strength straightening balm when I want to go straight. Otherwise, I use the secret weapon and go curly.
