If you experience hair loss, know you're not alone. One of the most gorgeous women in Hollywood does, too. Keira Knightley, who is a beauty icon in her own right (she's even the face of Chanel!), admitted to InStyle UK that she suffers from hair loss and has to wear wigs.
Keira said, "I have dyed my hair virtually every color imaginable for different films. It got so bad that my hair literally began to fall out of my head! So for the past five years I've used wigs, which is the greatest thing that's ever happened to my hair."
