Katy Perry’s Green Hair: According To ‘Girl Code,’ This Is What It Really Means

From Rihanna to Miley Cyrus, a celeb hair transformation means a lot more than a haircut.

Katy Perry ushered in spring in an unusual way this week. The “Dark Horse” singer switched up her staple black hair for some green tresses on Monday — “slime green” to be exact.

Proudly posting the results on her Instagram, Perry wrote. “SLIME GREEN FOR SPRING by my bb’s@neeenaboo & @brantmayfield at the@mcmillansalon.”
