In the time it takes us mere mortals to decide whether we are can brave a bob cut or can cope with the potential trauma of a fringe - Rihanna has already got through three different styles, and nailing each one perfectly!
So, as we aren't always daring enough to go for a radical hair overhaul ourselves, what could be better than giving your opinion on the best looks for your favourite celebrites.
From Jennifer Lawrence to Miley Cyrus - we look at the most daring hair makeovers and ask, what is your favourite look?
VOTE ON ALL THE STYLES BELOW
Lucy Mecklenburgh
The TOWIE star has been through a bit of a style evolution of late, sharpening up her look and impressing style pundits. But last night she showed she was still staying true to her Essex roots, unveiling her new extensions to promote brand Easilocks.
Miley Cyrus
It's been a phenomenal year for former Mickey Mouse club member, Miley, who has grabbed headlines the world over for her naked performances and on stage antics. And as her behaviour has changed, so has her hair - going from a sleek and soft cut to a short, edgy style that perfectly frames that mischievious face of her.
Beyonce
Beyonce is the queen of the stage, and her mass of thick, curly hair is as much a part of her high volume performance as the costumes. But Beyonce shocked fans earlier this year when she shared a picture of a short, pixie crop. She has since worn her hair in a longer, soft bob. But which is your favourite Beyonce style?
Jessie J
Jessie J has got braver and bolder with her look step by step, starting long and poker straight (right), moving on to a flicked in bob and then braving an almost bald look after shaving her hair off for Comic Relief.
Victoria Beckham
Yes that IS Victoria Beckham in the middle, back in 2007 and long before her credentials as a serious force for fashion were realised. Victoria is a hair chameleon, having braved a pixie crop, spiky brunette short do, sharp bob and who could forget that amazing bleach blonde 'pob'!
Jennifer Lawrence
She recently unveiled a new short crop, but while Jennifer Lawrence hasn't been quite as brave as her character Katniss Everdeen when it comes to hair, she has still experimented with a chunky fringe and an elegant, layered updo.
