No one has worn it but Marilyn." Sydney Guilaroff was a hair stylist during Hollywood's Golden Age who was the first to receive on-screen credit in films. He worked for more than forty years at the Metro Goldwyn Mayer studios on more than a thousand films, and was instrumental in crafting many of the hairstyles which became the signature looks for numerous film stars. Guilaroff was a friend, stylist, and confidante to many Golden Age stars including Greta Garbo, Joan Crawford, and Audrey Hepburn along with Marilyn Monroe, and styled Marilyn's hair for her funeral in 1962.
