Britney Spears is getting back to her roots, at least when it comes to her hair. The pop star debuted new chestnut strands at Elton John's 21st Annual AIDS Foundation Academy Awards Viewing Party. It wasn't the first time she switched from her better-known golden locks to darker ones. But it was a bold move, considering she has stayed tried-and-true to her flaxen mane since 2009.

Of course she's not the only well-known face who has recently switched it up when it comes to hair color. She is the only one, however, who has gone from blonde to brunette. More women these days seem to be responding to the sunless days of winter by lightening up.
One celebrity who surprised us the most with her new color was Zosia Mamet. The Girls star, normally known for her straight brown center-parted lengths, is now rocking textured waves in the yellow hue.
Another style icon who swapped her jet black mane for platinum? Leigh Lezark. She looks like an entirely different person without her raven-colored bob, though she has said her natural hair is curly and blonde.
Fashion insider Ulyana Sergeenko is keeping up with the trend, as well. She dyed her auburn hair peroxide white, perfect for standing out among the street-style stars during fashion week. She looks like an ice queen in a winter wonderland.
