What is a good hair product for thin curly hair to keep it straight in high humidity?

I work in a restraunt and by the end of my shift my hair is a wreck. I use the nexus smoothing creme and a good flat iron but i need ideas of other good products for around the same price. Are there any sprays I could keep with me and spray to avoid a frizz fest?What is a good hair product for thin curly hair to keep it straight in high humidity?
I have curly hair too and when I straighten it I always have to use John Frieda products. Right now I am down in Florida for Spring Break and I have been using the new Weather Works products and they have been doing a really good job keeping the frizz to a minimum.What is a good hair product for thin curly hair to keep it straight in high humidity?
