Drying hair

I'm struggling to keep my hair curly when I dry it naturally. I use the CG method and it's beautiful and curly, then by the time it dries, the curls sort of collapse into frizzy waves.

I'm not touching my hair as it dries so I'm wondering if this is a case of not using enough gel?

Also, once my hair has dried frizzy, how can I defrizz it without washing?
