Katy Perry, Lady Gaga and Rihanna are in a special club. The first ladies of pop music change their hair color, texture, length and style with incredible, strand-damaging frequency. But that thanks to the miracles of modern science and cosmetics, they can have bangs one day, a bob the next and butt-length Rapunzel locks in a matter of minutes.

Perry, a natural blonde, burst onto the scene with her signature Bettie Page bangs and glossy, raven locks. In the past two years, she's ditched that Old Hollywood glam look and has been blue, pink, purple and many more colors of the rainbow.

The 'Wide Awake' singer may be committed to her boyfriend John Mayer, but she is not committed to any style, shade or shape when it comes to her follicles. Check our collection of some of Katy Perry's best hairstyles below!
