Nicole Richie is the latest celebrity to join team pink hair, revealing her newly dip-dyed ends on her Twitter account with the caption, "Tickled Pink!" Nicole is now among a growing group of stars brightening their hair this season, as January Jones, Brooklyn Decker, and Coco Rocha have also tested out the trend. Looking to get a similar pop of color for Summer? Try these vividly hued Sultra clip in extensions ($18), which will blend in nicely with curly or straight textures. Or if you want a dip-dyed look like Nicole, reach for the hair chalk. Both of these methods are temporary remedies to your bright hair craving that will work on any hair color.
