Even celebrity kids, such as Zahara Jolie-Pitt and Coco Arquette, have had fun with the look. And while blue may be on a streak now, plenty of other celebrities have exhibited sapphire strands in the past — Lauren Conrad, Bai Ling, Juliette Lewis, Kate Bosworth, Kelis, Selma Blair, Jada Pinkett Smith, and Gwen Stefani — so don't expect this trend to end here.
No longer does the term "blue hair" conjure images of older ladies with hair set and sprayed to helmet-head proportions. Instead, the blue-haired look of 2012 takes a fresh, youthful approach, as certain stars have demonstrated as of late. Most recently, Jaime King debuted a bevy of blue strands, alternating in color from baby-hued to royal. Then there's Katy Perry, who has displayed just about every shade of blue in hairstyles ranging from crimped ponytails to blunt bobs. In addition, Selena Gomez got in on the trend earlier this year with electric blue and purple strands woven underneath.
