Cool is an understatement when it comes to these hairstyles.

'Bed-head' hair, 'french-girl' hair, 'rock-chic' hair - Whatever you call it, the fact is everyone wants it. It's cool, undone, effortlessly stylish and the staple look of every modern day It-Girl.

To get you inspired, we gathered our most recent favourite rock-chic looks from the 'gram.

CARA DELEVINGNE

Fiercer than ever, Cara Delevingne took the ultimate hair dare this year by chopping it all off. Literally. Although she's usually spotted donning a buzz-cut, who could forget that silver-sprayed bald scalp at the Met Gala? Love it or hate it, Cara's clearly embracing her new found style, and in true rock-chic fashion, couldn't care less what anyone says.

EMILY BADOR

What's not to love about model Emily Bador’s super blunt fringe and even longer, straight locks? It's the perfect combination of quirky, stylish and edgy.

She's a perfect example of how a fringe can transform your whole face. But if you're feeling nervous, there's no harm in testing the look out with a faux fringe.

LILY-ROSE DEPP

Channelling her French side with THAT effortless yet gorgeous beauty most of us can only dream of on our best of days. Rocking tousled, 'barely-there' waves, Lily-Rose has got the nonchalant look down to a tee.

Pair with a heavy, dark eyeliner to amp up the attitude.

RUBY ROSE

Tats and cropped hair - Ruby Rose is plain bad-ass.

ALEXA CHUNG

You know you've made it when your hair becomes a signature look. Choppy and effortless looking, Alexa’s hair has both 'It-Girl' and rock chick vibes.

KATE MOSS

And lastly, the Queen of rock chicks herself, Kate Moss! Her hair is never too 'done' and is the perfect example of how rock-chic is timeless. Her style back in her teens is still as relevant today as it was back then, earning her fashion and beauty icon status.
