Sure, they're rich and famous and lead fabulously glamorous lives but sometimes even while they're busy jet-setting around the globe, A-list celebrities can get caught in beauty ruts -- just like the rest of us.

You know how your best friend Michelle has had that same old feathered Sammie Jo Carrington haircut since 1987? Well, flip through the pages of any celebrity magazine and you'll quickly realize that there are more than a few big name stars who are stuck in that same sort of groove. Sure, there are some, like Drew Barrymore and Scarlett Johansson, who mix up their hairstyles and color with alarming regularity, but many others have stayed with the same look for most of their careers.

Clearly, they (or their stylist) found a look that worked for them and they're sticking with it come hell or high water. Whether it's because they think the public only wants to see them a certain way or because they've become complacent, some just don't seem to want to transform their signature celebrity hairstyle in the slightest.

Well, in the interest of shaking things up a bit, we'd like to (gently) suggest that a certain few should step out of the past and grab hold of a bold new look. To that end, we've combed through hundreds of photos to find the seven female celebrity hairstyles we think could really use a boost. We're not talking about overhauling their fashion senses or revamping their entire makeup palettes � we just want to recommend a new hairstyle and/or color that (we think) would work wonders for modernizing their entire appearance.

So, just which celebrity hairstyles could use a little love? We've pegged Lindsay Lohan, Carrie Underwood, Rachel Zoe, Angelina Jolie, Demi Moore, Courteney Cox and, yes, even Jennifer Aniston. Curious to see what they'd look like transformed? Start clicking and see if you agree that they could stand to embrace some big time change.
