John Francis Barrett (1957–2023) was an Irish-born American hair stylist. 
Biography.
Born in Limerick, Ireland, to John Barrett, a laborer, and Philomena (Maroney) Barrett, a homemaker, he was one of ten siblings and grew up in poverty. Around the age of 13, Barrett moved to London in search of work and initially earned a living selling souvenirs on Oxford Street.
Barrett began his hairdressing career by responding to an advertisement for an assistant position at Michaeljohn salon, which served clients such as Mick Jagger and Liza Minnelli. By the mid-1970s, he had established himself as a stylist. An encounter with Elizabeth Taylor, who was seeking a stylist named John and selected him for an appointment, further increased his profile.
His career spanned several major cities. Barrett spent part of the 1980s in Los Angeles, returned to London, and settled in New York in the early 1990s, where he worked with Frédéric Fekkai. Following an interaction with Dawn Mello, then-president of Bergdorf Goodman, he secured a penthouse salon space in the store's former founder's residence. Later, he introduced salon concepts such as a "ponytail bar" and a "braid bar," and offered personalized services, including house calls. Between 2014 and 2016, he operated a satellite salon in Palm Beach, Florida.
Barrett was open about his struggles with alcoholism, which he overcame in 1987. He organized charity events and provided counseling to individuals dealing with addiction.
