How can i scrunch my hair and make it last?

alright so my hair is kinda weird, what i mean is that it holds curls nicely, but when i scrunch it, it falls after a couple hours. I usually follow juicystar07's (youtube)) way of scrunching. It works really good but it just falls, I use hairspray but even that doesnt work. please if any of you guys out there can help me i will love you forever haha:) thanks
