Spritz a small amount of light hairspray on your hair before curling it. Then use a freezing spray after you are done styling. Also try using a sulfate free or curling shampoo. Avoid products that contain silicone or other ingredients ending with -cone because they can weigh your hair down and pull the curl out faster. I know you said your hair is naturally straight but check out this site for products and info on keeping curls www.naturallycurly.com

I've also read somewhere to avoid products labeled as humectants because they can sometimes weigh fine hair down.

p.s. if you are using suave shampoo and conditioner that maybe be part of the problem
haha ok listen, I got a perm. That's a great alternative too..but anyway, If I were you, I'd curl it at night, then mouse it up, then use special gell for curly hair, then clip it up, hairspray it and sleep on it and Voila =] curls out to wazu!
