Okay so I have naturally curly hair, but not those curls. I mena the ones when I blow out my hair and try to add waves or curls with the curling iron. When I do this within no time the curls/waves are falling out. I've tried "steam" curling irons. I've tried spraying hairspray while the section is still on the iron. I've tried anti-humidity sprays and products. Why can't I make them stay?!
Try Kenra Molding Creme. It's very strong and takes some practice, but it holds like crazy. Might get crunchy if you use too much. But, if you use the right amount, this stuff kicks butt.
When you take them off the curling iron, pin them to your head with alligator clips until they cool. Also, use a holding gel or cream first, and you should be okay.
