Kristin Cavallari was a brunette for, um, NO TIME AT ALL. Even though The Hills star Tweeted that she had dyed her blond hair a few shades darker and premiered the look on August 11, she got rid of her darker 'do quickly. Today she stepped out with lighter locks (more like her natural shade) when she showed up to a design session for ShoeDazzle.com in Los Angeles — not even two weeks she debuted her darker look! Could she have regretted her decision to go to the dark side? Or perhaps blonds really do have more fun? Either way, for dying her hair so much, it sure doesn't look damaged, so that's a plus.
+ Do you like her return to light color? Have you ever dyed your hair three times in one month?
