We love when celebs switch up their styles, especially when it's in the hair department. Michelle Obama kicked off the latest trend with her rockin' new bangs. The First Lady debuted her new 'do during the Inauguration Weekend. Next up, Vanessa Hudgens! She's gone from long to short and back, but this time around she's going with a bob, and we like! Another celeb that's workin' the bob? Nicole Richie showed off tons of pics on Instagram of her locks getting chopped! Whose new style do you like best? Anyone you don't like? Let us know!
