Townsend first tamed Olsen's tresses for a high school dance: "It was my freshman year winter formal, and Mark had just done my sisters' [Mary-Kate and Ashley] hair; we were all going to the same dance," the 26-year-old tells THR. "He gave me an updo, and I had the best hair in my class." Fast-forward 12 years to the twosome traveling to Tokyo for the star's Avengers press tour. "We were inspired by a woman at dinner the night before the premiere," recalls Olsen. The result? An unconventional French twist with fanned-out hair at the ends. The look ("one of the all-time favorite hairstyles I've ever done," says Townsend) worked with the actress' black silk faille dress and white gold and diamond jewelry, both Dior. "The dress was a new take on a very classic silhouette, so I wanted the hair to feel the same way," says Townsend. The Instagram devotee posts his #MarksEyeView pics for 32,900 fans. "I take pride in the updos I create for red-carpet events, and through Instagram I can show my followers close-ups of the hairstyle from different angles."
