He opened his first salon in 1954, when hair was high and heavy, set on rollers, then teased (backcombed) and sprayed into place. In the 1960s, Sassoon shocked the fashion world with his geometric cuts which required little styling and fell into place perfectly with little effort on the part of the wearer.
The styles were perfect for the fledgling women's liberation movement. Allure magazine editor-in-chief Linda Wells said, "His timing was perfect. As women's hair was liberated, so were their lives."
Sassoon changed the world of hairstyling and beauty and became the most famous hairdresser in history.
He moved to Los Angeles in the early 1970s to advance his line of hairstyling products and made the city his home. He sold his business interests in the 1980s to become a philanthropist.
