She did it!

Jessie J shaved her head for charity. She went through with it, buzzing her silky, shiny, glossy bob with blunt bangs until there was nothing left. She's now rocking peach fuzz. And guess what? She looks gorge, all glammed out with big gold hoops, perfectly curled and fluttery eyelashes and glossy pink lips.

Not everyone can pull off the down-to-the-scalp look and still make jaws drop, but that's just what the 'Price Tag' singer does.

The singer tweeted the image and thanked everyone for their huge show of support.

In honor of the British diva's brave act -- we're calling it brave since most women are deeply attached to their hair -- PopCrush looked back on some of Jessie J's best coifs, reminiscing about her beautiful-haired head, to borrow a phrase from Kristen Wiig's Annie in 'Bridesmaids.'

Jessie's signature, glossy black bob, with ruler-straight bangs, was angled at the chin and framed her beautiful face. It was her most definitive style.

She also rocked shoulder length, chocolate brown and bang-less locks last year. It's a little bland when you compare it to her blunt, dramatic bob, which certainly stands out more.

Jessie J also got in on the ubiquitous dip dye trend, lengthening her bob at the ends and dying them golden blonde. The increased length was likely due to extensions, but she kept her straight bangs as usual.

The 'Domino' diva also tried a magenta version of the dip dye 'do.

The sexy singer was beautiful with Old Hollywood waves. It's not a look she attempted often, but we loved that it was a change of pace and unexpected.

It was 'I Dream of Jessie' and opposed to 'I Dream of Jeannie,' thanks to this sleek, slicked back, high ponytail. She paired it with Cleopatra-style, winger eyeliner for an overall dramatic look.
