Nicole Richie's Back to Being a Blonde!

Nicole Richie has a new/old hairstyle.

After a year of living as a brunette, Paris Hilton's erstwhile bff has returned to her formerly blonde roots with a little help from Joico celeb stylist George Papankikolas.

And, in typical star style, she did it super-quickly. " “Normally I recommend transitioning from dark hair to light hair over the course of several months,” Papanikolas said in a statement issued today, “but Nicole was ready to go back to being blonde sooner than later, so we did it over the course of a week."

But, what about damaging the hair? To offset any harm that might befall the hair shaft, Papanikolas strengthened Richie's hair with JOICO K-PAK Deep-Penetraiting Reconstructor and used a lightener that contained conditioners to prevent breakage that can happen when bleaching hair.

What do you think about the new style? Prefer Nicole blonde or brown? (Or, could you not care less?)
