Rites of Beauty: Sienna Miller The actress Sienna Miller on the ups and downs of her hair. When I was a teenager and watched Catherine McCormack in Braveheart I thought she was the most beautiful thing I'd ever seen. I was captivated by her undone, windswept Highland hair, but it was in stark contrast to my own, which went through several horrible stages. First I experimented with rave colours, dying it pink, then pink with white streaks, then green. I even tried cornrows, which was not a good look on me, especially as I had braces at the same time. Then, when I was 16, I took a picture of Winona Ryder into a branch of Toni & Guy in an effort to achieve her pixie cut. But when I walked out I looked as if I had a helmet on. My boyfriend at the time opened the door and closed it in my face. I don't think I'll be trying that again. Fortunately nowadays I go with whatever hairstyle is the lowest maintenance. I think I'll be avoiding the cornrows, then. Sienna Miller is the face of Boss Orange, which has been launched in a limited-edition version to support Unicef's Schools for Africa initiative (boss-fragrances.com).
