How to scrunch african american hair?

i have permed my hair, but it's gotten so damaged that i'm trying to stop straightening it. i have thick hair and whenever i just blow dry it with a diffuser and scrunch it, it get's frizzy. i had a john frieda frizz ease that i use, but my hair still gets frizzy. how should i properly scrunch my hair where it looks more naturally rather having that crispy feel to it and where it isn't frizzy?
