Think your only hair color options are blonde, brunette, and red? Think again! Across the spring and fall runways, a new hair dye trend has taken hold. From turquoise to lavender to hot pink, colorful tresses are in. Models at Giles Deacon and Proenza Schouler’s Spring 2010 shows sported loose, palely tinted hairstyles; at Vena Cava and Cynthia Rowley’s Fall 2010 shows, models wore ponytails with bright-colored streaks. However it’s done, this multihued look is fun, funky, and modern. Feeling bold? Try Streekers dye (www.streekers.com) on hair extensions to add your own whimsical pop of Crayola color to your everyday style.
