Yes, covering means no more bad hair days, really.
You get to replace them, however, with bad scarf days. Days when no matter what you do, you can not get the scarf to lay right. It folds funny, it slides, the snoody part in the back magically appears to one side of you head, as opposed to the back, where it should be.
And you wind up spending ten minutes in the bathroom at work fixing it.
