Why should your Christmas tree get all the attention? Take a tip from Beyoncé and Ke$ha, women who know how to make a head-turning entrance, and adorn your hair with sparkling gems. These Glisten Hair Charms come in five colors, from rainbow to clear. You apply the sticky strip of crystals with a flat iron and they stay in place until you shampoo them out. Remember a little glitz goes a long way; decorate just a few strands near your face.
