Any advice on hot rolling fine hair

I am looking for some advice on hotrolling fine hair. The other day I was doing a shoot on a model who had beautiful hair, but it was very fine and her length was to her mid back.

I hot rolled her hair in preparation for an upstyle the editor wanted. I used a L`Oreal protective spray on each section then rolled the hot roller onto it, then I sprayed the entire head when all rollers were in, but the curls fell out almost immediately.

Can anyone suggest ways to do this so that the curls will last a lot longer. I thought about a little mousse distributed through the hair before rolling? Any suggestions?

another one to try is caruso steam curlers.

the pro-rodeo court uses them to keep their hair curly for shows and we have all types of hair in that bunch. They hold curl well and withstand the ladies riding thru the arena on those horses. Their hair looks good all night.

like demodoll said, use lots of hairspray. just be careful when you go to brush it out. You may cause breakage of your hair.

Whenever I style mine, I let the water from the shower break down most of the goop, then wash and use a wide pic with lots of conditioner to get the tangles out.
