Maye Musk, 68, may be one of the most in-demand models for New York Fashion Week next month. The glamma grandma, registered dietician nutritionist, and mother of billionaire, Elon Musk, has been working in fashion for more than fifty years; however, it was not until she started letting her hair go gray that she found true success. “When I was approaching 60, I got sick of being blonde, so I decided to stop coloring my hair. I grew out the gray and I cut it short. People said, ‘You’ll never work again with short gray hair,’ but it came out white and everybody loved it,” she shared with Harper’s Bazaar. “I got a billboard in Times Square for Target and a billboard in Madison Square Garden for Verizon and my career took off. I started getting a lot of high fashion work then, too,” she continued. The brand ambassador for Atelier Swarovski has signed with top modeling agency, IMG, worked for beauty brands, Clinique and Revlon, shot spreads for Elle and Italian Vogue, and has even appeared in a Beyoncé video. “Looking back, letting my hair go natural was an amazing decision because I started getting major ad campaigns. I also signed with agencies in Europe and travelled to many different cities, which I loved. People would stop me in the street and say they loved my hair.” Musk has become the poster girl of the Greynaissance movement, which has emerged from a new generation of fashion and beauty consumers who respond better to products advertised by women their own age.
