Need help with costume wig! Sandy from Grease.....? - sandy grease wigs

I bought the wig, fat sand and gravel all. I know I need a bit of fluff, but the peak, short hair, he looks like a mullet instead of curls and loops are rather flat, and some are straight. In the film, his hair blowing and even with the picture of the wig. Can I brush and recurl? No idea how they look as good as possible? "
