Do you want the look for yourself?

Matrix celebrity hairstylist George Papanikolas told the media "Anyone who is fashion forward [can wear purple hair]. Considering purple hair doesn't happen in nature, you don't need to be too concerned with your skin tone, but you will need to adjust your makeup. Too much and you can start to look like a clown. Nicole tends to keep her makeup natural, which is a nice combination." He adds, "The upkeep is a full-time job. The roots need retouching every few weeks and the pastel toner every few days, otherwise it turns into an uneven platinum blonde."

Papanikolas did not do the do for Nicole Richie.
