Scarlett likes to play with hair colour

Scarlett Johansson, who recently ditched her blonde locks in favour of a fiery auburn hue, thinks altering the colour of her tresses is one of the easiest ways to update her look.

She said: "I go to the hairstylist every three weeks. To me, hair colour is something fun to play with. If you want a different look, it's easy enough to alternate."
