It finally happened, folks: Kaia Gerber officially ditched her signature light brown hair for an unexpected sunny blonde hue that screams "surfer girl." Gerber debuted her new look over the weekend in a chic-as-hell Instagram selfie with her hair worn deliberately messy and falling halfway in her face. The 18-year-old model paired her selfie with the simple caption: "zoom bleach," likely referring to the fact that she had to bleach her hair in order go lighter. Those commenting on Gerber's new hair color include Lady Gaga's makeup artist Sarah Tanno, Queer Eye's Tan France, and Los Angeles-based hair colorist, Daniel Moon.
