Celebrity Beauty Trend: Undone Updos

Updos have a reputation for being high-maintenance and totally complicated, but these curly hairstyles are anything but. The less perfect, the better, and best all of, unwashed hair is the key to creating a cool 'do. That's right—just skip the shower and rub in a little dry shampoo.

Take Chloe Moretz's playful side bun, for instance. Instead of pinning back the short strands, she took a curling iron to them and embraced the ringlets. Elizabeth Olsen went for an even curlier look that would be easily achieved with a set of small hot rollers and a handful of bobby-pins. Impossibly easy and glamorous? This coif is a keeper.
