The I-woke-up-like-this look is a sight to behold, and nothing is more quintessential to the blithe approach than bedhead. Trading in salon slick for homespun cool, artfully-disheveled styles are permanently dispelling the myth that you have to wash and brush your hair everyday. Allow these chic stars to inspire you to embrace the tangled, tousled remnants of yesterdayâs hairstyle. Dry shampoo, a teasing brush, and a little insouciance? VoilÃ ! Your coif is a strategic hot mess.
