I was pondering this myself. If I wash my hair at night, by the next afternoon I look like a greaseball. My super fine, short, straight and dark blond hair looks totally crazy if I don't shampoo it. (I've tried just rinsing it with water before, and that's a no go.) I would like to try a less harsh option than shampoo though. Some hair types don't do well without regular washing :(.
