From her outfits to her hair, Jessie J loves switching up her look, and she's been going crazy with color on her buzzed strands this past week.

On Wednesday, July 17, the songstress posted pictures on Instagram of her formerly bleached blond hair in a shocking shade of purple. Then, the following day, Ms. J changed her hair color yet again, this time to a turquoise blue.

When she swapped her platinum locks for purp, she posted an Instagram pic for her Heartbeats, writing, "Purple purple purple purple purple purple sucker," along with a note about how much she loved her outfit -- by the way, it's from American Apparel's collaborative collection with L.A.-based artist Kesh.

The next day, Jessie posted her blue-haired pic, writing, "Blue hair don't care... Just for today? Lol." We aren't totally sure, but we'd say that Jessie is using washable hair dyes. It's only way she could effortlessly switch between such bolds colors in such a short time frame.

In addition to her hair (scroll down for more pics), Jessie also updated fans on some new music via Instagram. She penned a song called 'Hero' for the 'Kick-A-- 2' soundtrack, and shared a 50-second snippet of the aggressive, rock-inspired pop track, which you can listen to below.
