British celebrity hairstylist and beauty entrepreneur John Frieda has died aged 75.

His death was announced on the official Instagram account for his eponymous hair salon.

“It is with heavy hearts that we share the news that our dear John passed away peacefully … surrounded by his family,” it said.

“John was more than a mentor to us; he was a true icon of the hair industry. He was the person who taught us everything, believed in us, and made us better.

“His talent and passion touched so many, and his legacy will live on in every single one of us. We will continue to do him proud.”

Frieda’s stepdaughter, Asia Agnelli Lagrange, also confirmed his death on social media.

Sharing a series of photos of them together over the years, she wrote: “Today we lost the best man to ever exist.

“I share this because I know he touched the lives of so many.”

Born Alan Howard Frieda in London in 1951, his father was a hairdresser who owned a salon in Ealing, while his grandfather was a Fleet Street barber.

After working for his father, Frieda joined the London hair salon House of Leonard and became the assistant of Leonard Lewis – who was credited with creating the haircut that launched the career of model Twiggy.

He went on to work for British Vogue and Harper’s Bazaar, as well as with Lewis’ clients including Twiggy, Jackie Onassis and Mick Jagger.

In 1976, Frieda invented the “Purdey” hairstyle – creating the bowl cut for actor Joanna Lumley after she asked him for a schoolboy’s haircut for her role in The New Avengers.

That same year, he opened his own salon at the age of 25, and also married his first wife, Scottish singer Lulu.

Throughout the 1980s Frieda went on to work with American haircare executive Gail Federici to create his own product line, launching Frizz-Ease in 1988.

After separating from Lulu in 1991, he then married Frances Avery Agnelli in 2019, after initially meeting in 2002.

That year he also sold his haircare product company to Japanese conglomerate Kao for $US450 million, but retained his five salons – two in London, two in New York and one in Los Angeles.

Throughout his career, Frieda worked with other clients including Diana, Princess of Wales, Madonna, Nicole Kidman and Scarlett Johansson.

He is survived by his wife, four children and two grandchildren.
