When normal people get their hair cut, it usually leads to either compliments or total mockery. But when celebrities decide to switch up their hairdos, the whole world suddenly has an opinion.
Take for instance Beyoncé's pixie cut last week, which caused nearly everybody to freak out about why she did it. But it Beyoncé isn't the only one who makes waves whenever she pays a visit to the hairdresser:
2007 was not the best year for Britney Spears. Shortly after splitting with Kevin Federline the singer made headlines by shaving off her golden locks, leading to speculation that she was on a brink of a breakdown.
When her marriage to Ryan Phillippe fell apart, Reese Witherspoon transitioned into her single status by showing up with bangs at the 2007 Golden Globes.
Following her split from Heath Ledger in 2007, Michelle Williams chopped off her demure curls and stepped out in a strong, tapered cropped cut. The adorable look is now her signature style.
This sleek bob appeared shortly after Anne Hathaway's controversial breakup with real estate developer boyfriend Raffaello Follieri, who was later charged for defrauding investors for millions of dollars.
There's no denying that Marilyn Manson has a "type." So Evan Rachel Wood started dating him in 2008, she also adopted a new goth image. Once they split, Wood returned back to her natural blonde.
Kim Kardashian dark glossy hair is pretty much her signature look. She decided to experiment with blonde highlights after her split from football player Reggie Bush, and became almost unrecognizable.
Kelly Osbourne's has certainly come a long way from her days as a wild child of rocker Ozzy Osbourne. These days this edgy fashionista is at the forefront of fashion. Her hair has gone from black to lilac to grey (prompted by her split with Luke Worrall) and now she's back to a vibrant blonde.
Emma Watson decided to distance himself from her Hermoine days by getting rid of her long locks and stepped out with a close-cropped pixie cut.
Miley Cyrus has made it clear that she's no longer Hannah Montana. The former Disney starlet traded her goodie-too-shoes image by opting for a boundary-pushing mohawk. Trying too hard perhaps?
No celebrity haircut lists would be complete without mentioning the most iconic celebrity hair transformation of the century. And that title belongs to none other than Justin Bieber, who famously traded his shaggy do for something less boyish in 2011. The trimmings were later put up for auction with the profits being donated to charity.
