What can i do to keep my hair perfectly scrunched?

whenever i scrunch my hair ( its naturaly kinda wavy and poofy)

it'll stay nice 4 a while but then it'll fall flat and get really frizzy and straight what should i do?

ooo this is how i do it

when my hair is sorta damp when i come out of the shower i put a little bit of gel in my hand and scrunch the hair

then i put the hair in a bun on the top of my head and spray hairspray it used to work perfectly but now it wont so how should i scrunch it so it stays?
