Throughout all the press coverage of Britney's divorce, I've been struck by her gorgeous, pulled-together hair. Ditto for Reese Witherspoon. It's a lesson for all of us: It's easier when you're feeling down to just pull your hair back and forget about it, but taking the time to blow-dry, straighten or get a new cut or color may be just what you need to start healing. Don't do anything drastic, though. It's tempting to cut off the hair your ex loved, but if you're doing it out of spite, you'll likely regret it. Besides, there's no better revenge than great hair—agree?
