It was the beauty anthem of 2010. And just as much fun if you were 15 or 50. Willow Smith's "Whip My Hair" made braids and hair sculptures the hottest trend—until she showed up at a holiday tree lighting with cool candy cane stripes. And then just as quickly, Will Smith's daughter rocked the red carpet at Z100's Jingle Ball in NYC with a bowl cut. (This 12-year-old's taken more chances with her look than most people will in a lifetime.) And while we may not rush out to copy her current Dorothy Hamill haircut, we can't wait to see what she does next!
