These Are The Hairstyles That Defined 2013

Thanks to social media (and cocky celebrity hairstylists), it only takes a few seconds to find out which stars are sporting a new cut or color. One click on hashtags such as #Beyoncepixie, #KateMiddletonhair or #MichelleObamahighlights surfaces months-long discussions and debates about some of 2013's most memorable hairdos.

But all the Twitter and Instagram talk isn't just a bunch of fans and haters going back and forth. There's also some serious hair education happening, including explanations of Rihanna's American Music Awards doobie wrap and Bradley Cooper's "American Hustle" perm rollers.

There's no need for you to scroll back through an entire year's worth of social media alerts. Below is a list of hairstyles that defined 2013.
