How to get curls in my hair to stick?

I curl my hair with a flat iron, but the curls don't really hold. Is there anything I can do to make the curls stay throughout the day?How to get curls in my hair to stick?
you might not curling it enough. try to do it more slowly, take up more time (not so much that you burn your hair). then use just enough hairspray. if you use too much it will weigh down your hair and the curls wont stay and if you dont use enough it wont hold.How to get curls in my hair to stick?
use loads of hairspray.
hairspray :)when you wrap your hair around the curling iorn and spray it ..do this to each curl ... then at the end spray all over :)
