My (terrible, dry, fine, generally rubbish) hair looks better when it's washed, but from somewhere I have absorbed the wisdom that it is bad to wash your hair every day so I don't This means my hair goes from being just about OK to downright embarrassing from day to day.
Obviously, with my crap hair, I'm keen not to do anything which is bad for it, so have resisted the every day washing thing.
What's the truth?
