THE MOST DIFFICULT HAIR IN THE WORLD!

Someone please help! Relocated to GA and the humidity is killing me. I have long, Indian-like hair which gets about as straight as oriental hair with a good blow out. But when I do it (and 90%)of the hairdressers I go to, as soon as I go outside the humidity jumps on my hair and I have a frizzy mess before I get home. I've tried Gramham Webb's relaxing balm, and I notice that other companies offer this product, but I did not get the desired result. And another thing, I don't know who it works for, but those hair frizz serums with 2-3 drop indications do not work on my hair. My hair holds heat so well that you could burn yourself on it, and it gets stick straight. Could someone just tell me the names of some good products and techniques,I'll try anything!
