Help please, scrunching hair problem?

okay so i have really straight hair, and i am tired of straighting parts of it everyday. i really want to just scrunch it for i dont have to even really try. i have herbal essences totally twisted scrunching gel and the tousle me softly mousse, oh and also hair spray. i tried everything, tying it in a bun over night, just scrunching it, and all that. it kinda scrunches, but not curly, its like wavy. at what point does it look stupid from not being scrunched enough? any suggestions for scrunching my straight hair? thanks(:
