Nicole Richie Dyed Her Hair Purple, But She Isn't The First Celeb To Go Bold

Nicole Richie just dyed her hair purple. Really, really purple. And it's great. We love a bold choice that makes fashion lovers everywhere rejoice, and still leaves some people a little confused -- that's half the fun of fashion. And your hair is, after all, one of the most versatile accessories that there is. As wonderful as Nicole's new violet 'do is, she isn't the first celebrity to dye her hair a surprising shade. Here are 13 celebrities who have dipped into the crazy color pool.

Speaking of purple, Osbourne has been rocking a similar shade to Nicole’s for a while now. And we like it, as it is a vast improvement from some of Kelly’s previous hairstyles.

When in doubt, choose both fire engine red AND platinum blonde. Add cheetah print, Mickey Mouse, and cleavage to complete look.

Helen Mirren
