He probably never had a bad hair day in his life. Hairstyling pioneer Vidal Sassoon died of natural causes at age 84 on Wednesday at his home in Los Angeles. Sassoon began working in a salon as a “shampoo boy” and opened his first salon in London in 1954. Sassoon began to transform the rigid hairstyles of the 1950s and but didn’t become famous for his wash-and-wear hairstyles until the ‘60s. “My idea was to cut shape into the hair, to use it like fabric and take away everything that was superfluous,” Sassoon said in a 1993 Los Angeles Times profile. He eventually expanded to the U.S. before developing an eponymous line of shampoos and styling products and founding the Vidal Sassoon Academies.
