JUSTIN BIEBER
In his early career, Justin was known for his "swoosh" hairstyle. But as he got older, he wanted something a little different.

Of course Jennifer had a hilarious reason for her November 2013 hair change. "It just couldn't get any uglier," she quipped during a chat with Yahoo.
NICOLE RICHIE
Nicole has always been a colorful character, but in March 2014, she lived up to her reputation with this wild look.
BRAD PITT
We've seen Brad with tons of different hairstyles, from long and luscious, to short and spiky. But until earlier this year, we'd never seen him with this interesting 'do.
BEYONCE
She's often called a queen, but Bey channeled one of the Disney princesses with this look in May 2014.
Miley Cyrus was surprising fans long before she started twerking, Miley shocked us all in August 2012 when she traded in her old hairstyle for this drastic look.
JUSTIN TIMBERLAKE
Teen girls loved Justin's adorable curls in the early days of *NSYNC. Then, in early 2001, he made a big change.

Throughout her career, RiRi has been a hair chameleon. But the singer took it to a whole 'nother level with this look in June 2010.
BRITNEY SPEARS
Britney has changed her look a number of times since we first met her in the late '90s. And in February, she did it again.
ADAM LEVINE
Adam is irrefutably sexy, but the same can't be said for the bold new hairstyle he tried in May. Fortunately, it was short lived.
DEMI LOVATO
By now, Demi's wild hair colors are par for the course. (Maybe it's time she gave her hair a break with all those hues.) But it was this March 2014 change that really shook things up.
It's not uncommon for actresses to change their looks for a movie role, and that's exactly what Margot did in January for her role in "Z for Zachariah."
