Spotted: Nicole Kidman out and about with a brand new hair colour! The actress visited the Omega store in New York yesterday sporting a high ponytail in her natural red hair instead of her usual bleach blonde locks. Is this change for a movie role, Nic? Or did you simply get bored and fancy an image change? And it seems she’s not the only one with a bit of hair restlessness...

Scarlett Johansson can never decide on a hair colour either. In December she was light brown. In March she was red. In May, she went bombshell blonde for her Mango campaign. Two months later she was rocking an auburn mane, which turned to strawberry blond in August. Phew!

Meanwhile, Jessica Alba went similarly dye-happy earlier this month. The Sin City actress was spotted with no less than THREE different hair colours in one week, going from auburn to bright red and then finally a rich brunette having been blonde a few weeks before, (seriously, is she on the run from the police, or what?). More importantly, we don’t envy the amount of TLC Scar and Jess must need to protect their locks from all that dye… deep conditioning treatment, anyone?
