Anne Hathaway: The Oscar-winning actress colored her short hair platinum blonde. Celebrity stylist Sascha Breuer tells Us Weekly she blow-dried the hair on top "back and upwards," and the sides "flat to the head" to get the "slightly boyish finish."
Nicole Richie: The Fashion Star mentor dyed her hair a gray-blue hue with the help of celebrity hairstylist Luke Chamberlain. "I applied the hair paint using a tint brush and then combed the color through each section," he tells Us.
