A documentary about the life of the hair industry's most mythical figure will debut at the Tribeca Film Festival next month.

It is the first time Vidal Sassoon, who revolutionized hair with his geometric cuts 40 years ago and created countless iconic styles including the Mia Farrow crop, will be the subject of an exhaustive, autobiographic film.

Producer Michael Gordon, a hairdresser in his own right, came up with the idea for Sassoon's 80th birthday - about the same time that the letter received one of Britain's highest honors, the Commander of the British Empire medal - and the fact that he is now 81, and the film is still in the makings, is proof of Gordon's "meticulousness rather than procrastination," as he says.

For the film, the crew revisited places Sassoon hadn't been to in decades, and scenes were shot on location in New York, Los Angeles, and London, among others. 

The film aims at one goal: explaining why Sassoon of all hairdressers became the most famous one. "I think his fame is largely due to the fact that he spent the majority of his life teaching everything he knew to others," says Gordon. "Most people keep it to themselves - make the most of it while they can - their talent, their inventions, their ideas. But not Vidal - he made hairdressing better - made hairdressers all over the world better at what they do."

Tribeca Film Festival will run April 23 to May 1. Check the festival's website, tribecafilm.com, for screening times and tickets. A new book on Sassoon will be released simultaneously.
