Keira Knightley has revealed one of the less glamorous consequences of being an award-winning actress.

Most women and men have experimented with their hair at some stage, whether it through dyeing, straightening or blow drying, and then inevitably paid the price at a later date.

Knightley has revealed this too is the case for actors who are bound by the appearance descriptions their roles require.

Knightley has been wearing wigs for films over the past five years after dying it so much for various roles led to it falling out.

“I have dyed my hair virtually every colour imaginable for different films. It got so bad that my hair literally began to fall out of my head!” she told InStyle. “So for the past five years I’ve used wigs, which is the greatest thing that’s ever happened to my hair.”
