Nicole Richie Dyes Her Hair Purple. Among other hair news, Nicole Richie is once again in the spotlight, since she recently posted pics of her newly dyed purple strands. Pastel hair is still very much trending in the beauty world, but we haven’t seen quite as many celebs jumping on the cotton colored hair trend bandwagon as of late. While her new bold strands are quite the eye popper, sometimes a girl just needs a fresh start, so lilac strands may be just the thing Nicole needed to lead her into spring. Check out her new look after the drop.
