SHOULD I LEAVE MY HAIR ROLLERS OVERNIGHT? PICS HERE?

[LALALALA!]

I have a problem in the morning with my hair being flat and lifeless. I've tried using blowdrier and rollers for 30 mins and put hairspray!! but still after few hours it goes back to straight and lifeless. Here's a pic of my before and after:

So What should I do now? Should I leave the hair rollers overnight? will it make a difference?
