This has been quite the year in hair! It's no surprise that celebrities have been keeping their hairstylists busy with changes over the past 365 days, and each unexpected trend that emerged almost always inspired us to consider a new look.

As demonstrated by Nicole Richie, Beyoncé, and Lauren Conrad, the lob (aka long bob) proved to be the most-popular cut due to its ability to flatter every face shape, and hold that effortless "I woke up like this" wave so well. Perhaps in part thanks to Richie's lavender strands, pastel hues had a serious moment, with every star from Demi Lovato to Zosia Mamet getting in on the fun.

To wrap up 2014 and head into 2015 with style, we're taking a retrospective look at every single celebrity haircut and color change that happened this year.
