Some of the country's most famous hairdressers have spoken of how Vidal Sassoon influenced their own careers.
As they arrived for a memorial service at St Paul's Cathedral today, John Frieda and Nicky Clarke paid tribute to him as a unique individual.
Vidal Sassoon was a London-born hairdressing pioner, who invented the "bob" hairstyle which epitomised the Swinging Sixties. Some of his most famous clients were designer Mary Quant, the model Jean Shrimpton and film star Terence Stamp.
He also turned his craft into a multi-million pound industry, creating a network of academies and lending his name to various hair products.

From the East End, the War years in London to his swinging 60's Bond Street saloon, then back to London in the 90's.
He talked to London Tonight about why he loves London and why he moved back after 40 years to make the U.K. his main home.
Back in 2005, he spoke to hairdressing students on the programme and he talked to us about his iconic bob cut, that changed hairdressing and his life.
