High Concept Hair, on Call

A firefighter turned globe-trotting editorial hairstylist, the New York–based Marcos Diaz brings a delicate, high-concept finesse to the runway (Diaz is a frequent Guido Palau collaborator) and red carpet alike. “Diaz reps a black book’s worth of New York girls-about-town—from gallery owner Dasha Zhukova and editor Giovanna Battaglia to DJ Mia Moretti—for major events,” says Vogue.com Beauty Director Catherine Piercy.
