Anne Hathaway dyed her hair peroxide blond for the Met Gala red carpet. In one of the more punk moments of the evening, Anne showed up with a hair color that rendered her almost unrecognizable. A sexy smoky eye brought the Debbie Harry-inspired look to another level.

To achieve Anne's hair, celebrity stylist Sascha Breuer applied a golf-ball-sized amount of Wella Professionals Extra Volume Mousse to her damp hair. He then rough-dryed her strands with his fingers, sweeping the longer hair back and upwards and pulling the sides tightly back. Using Wella Professionals Bold Move styling paste, Breuer ran his fingers through the midlength and ends for a mussy texture. He finished with a mist of Well Professionals Stay Firm Finishing Spray.
