What's up with the hair?

I am watching a lot of French TV lately (and trying to understand, but that's a separate story :) and I noticed that their anchors hair style is more "free", I'd even say disorganized then the perfect to a "t" American TV folks hairstyles. I mean c'mmon - here when you watch TV it seems like they all just came out of hair salon! Thinking about it - seems like yet another cultural difference.. What's up with that? Do you feel perfect hair is a part for American success/sex symbol?
