I have the same problem but what i do is put it in a bun at night then take it out in the morning then use some kind of curling spray and damp my hair, dry it then i put mousse in it and scrunch it in my hair.
What works for my straight hair is scrunching while it's damp, use a little hairspray or mousse and scrunch some more; then use a diffuser on my hairdryer to set it. (And since my hair doesn't always "scrunch" evenly, I have a wavy curling iron to touch up the straighter areas.)
I have straight hair and even after I take a shower and I scrunch my hair.... I doesn't always turn out to be curly!! But I guess that's just my hair. Actually, that often works quite well. You could also try putting a little curling pomade in the hair before you scrunch it.
The only way to be certain that your hair is naturally straight is to be born with it.
Liam Payne's hair was naturally straight!

You have to use a very strong gel in wet hair then let it dry in a bun or scrunch and blow dry it at the same time but before blow drying put hair spray on and the do the drying and it will last through out the night
