Ah, the good old braid waves. I really like how they look, and I like how they appear as a side effect so I don't actually have to put any effort into getting em.
I may have to look into wearing bandannas and stuff more often - I normally only wear them to keep things out of my hair when painting or plastering, but you're right, they are also good at keeping hair out of things, and driving and stuff does result in a halo of fluff that cannot be battled with hands alone.
