Grazia Daily is happy. Keira Knightley is back on the red carpet this month to promote her new film 'A Dangerous Method', providing us with another round of visual delights – and not just sartorially speaking. You see, us beauty fans have become somewhat entranced by KK's hair. Okay, so her locks aren't famous for being Blake Lively bouncy or Rihanna quirky but that's kinda what we love. Because every time Keira hits the red carpet, she shows off a new way to wear her hair and for the less follically blessed among us, this means inspiration a-plenty. Whether it's a sleek and side-swept up do, like the one she sported earlier this month at the BFI London Film Festival, or a wavy bob to frame her pretty face, the actress knows how to mix it up in a forever feminine and always interesting way. And THIS is why we've taken the opportunity to compile Keira Knightley's Hair Hall of Fame...
