See every shockingly bright colour Nicole Richie has dyed her hair

We've been a fan of Nicole Richie ever since we first saw her on The Simple Life, and perhaps the only thing more colorful than her language has been her hair. Over the past 12-plus years, she's dyed her strands white, black, and every shade in between (including purple and blue!). Take a trip down memory lane and see all the hues she's tried so far.
