Since pop stars have armies of stylists and glam squads at their disposal, they can change their hair color, cut, length and texture on a daily basis or on a whim. If they want to go from short to long or from bangs to bangs-free or from black to pink, they can! So which pop stars have had the most dramatic hair makeovers?

Well, there's Justin Bieber's definitive and famous swoop bangs, which he abandoned for his James Dean pompadour. Or Katy Perry's penchant for trying every color of the rainbow in a calendar year. Oh and what about Lady Gaga's vacillation between long and short? Don't forget Jessie J's switch from Bettie Page blunt bangs to a buzz cut, which she did for charity. Or Miley Cyrus' punk rock pixie cut. Don't get us started on Rihanna's fickle follicles.

We've rounded up some of the most dramatic and drastic celebrity hair makeovers. The only constant is change for these peeps.
