Question for girls with wavy hair

[kddani]

As I'm getting ready for an interview that I have in an hour and a half, i'm having issues pulling my hair back. I have slightly wavy hair..... and I can never get it to be "bump" free when I pull it all back, or even part of it back. I'm definately no good at doing hair, hence why I wear it down all the time. I'm just wondering if there's any tricks or tools (sprays, gels, etc.) that help alleviate this problem.
