Keira knightley avoids helmet hair for chanel

Forever the fashionista, Keira Knightley donned a camel biker suit for the filming of the latest Chanel advertising campaign. Flitting around the streets of Paris, Keira certainly looked the part. However, as every biker chick will know, once the obligitory safety helmet is removed, there is the problem of helmet hair. Flat on top, windswept through the ends, it's never a good look. However, Keira managed to still look stunning even after several retakes. How does she do it!
