We first reported that Jessie J would be shaving her head for Red Nose Day way back in September, when the ELLE cover girl announced it on Twitter.

Now six months later the singer has done the unthinkable: she’s shorn off that glossy black mane. And we think she she looks pretty amazing.

One of pop’s greatest hair chameleons, Jessie J has tried myriad hair looks in the run-up to her big reveal. We spoke to her hair stylist Lyndell Mansfield about her decision to shave it all off back in September: ‘She’s done the tough thing, she’s done the slick thing, she’s done the coloured wigs thing, she’s done the dip-dye thing, she’s done the fringe thing, she’s done no fringe, she’s done curly, she’s done straight. There’s nothing left, really, except for having short hair or a shaved head’ So, where does Jessie go from here?

Mansfield told us, 'I've mentioned to her we can do some fun wigs to start with and play with colour in her shaved hair for a bit. But to be honest I can't wait to do some amazing short haircuts.'
