Good products for frizzy&curly hair?

I'm going to Vietnam this summer, (in ten days) & I have majorly frizzy hair. It turns into like a hairball when it rains. It doesn't rain during the summer, but it's like 100% humid. I use Frizz-Ease by John Freida, but I don't think that will be enough to keep my hair tame. Do you know any products that will help my hair stay normal & not really frizzy with a hot of humidity? Thank you in advance! :)
