Celebrity Hair Transformations 2017

Oh hey Ariana Grande with grey hair. Switching out her signature brunette half up half down ponytail, Ariana revealed a lilac grey new look on her Instagram with the caption: 'btw i (it's grey)'. We're feeling serious Kim K bleached blonde vibes...

Proving our obsession with Marion Cotillard's French chic style transcends more than just her cool brunette locks, the actress has debuted her new bleached blonde hair styled in no less than four braids, and we are here for it.

Poppy Delevingne debuted a brand new short tousled bob at the world premiere of Kingsman: The Golden Circle. A bold move for the traditionally long-haired model, Delevingne captioned a picture of her new bob on Instagram, 'Croppy Poppy?
The POBBY? 🤣💇🏼😂 #ShortHairDontCare@kingsmanmovie'.

Following a similar hair trajectory to sister Cara, should we expect a bleach blonde buzz cut next? Watch this space.

Another addition to the Lob club, Pippa Middleton swapped her long hair for a choppy bob which she debuted on a bike ride through London.

Lena Dunham underwent a hair transformation from brunette to bright red courtesy of colourist Lena Ott. Documenting her hair journey for Vogue, Dunham commented, 'This is no sad bottle job. This is red hair with purpose, the kind I've been searching for. For the first time in months, I feel deeply in my body, in myself.'

The Prince of Pop's daughter unveiled a new, sophisticated ombré do at the Teen Choice Awards last night. Swapping her all-over bleach blonde Madonna-esque bob for smokey grey/brown ends and darker roots, Jackson might just be pioneering what we're naming the 'sombre' hair colour trend.

Modern Family actress Sarah Hyland traded in her beachy blonde lob for long brunette locks courtesy of her go-to hair stylist Nikki Lee.

Swapping her natural textured hair for orange and pink sunset braids, Alicia Keys' new look is fire (literally).

Did Sarah Jessica Parker just return to the Carrie Bradshaw bob? Answer - yes and no. The SATC actress did chop her usually long balayaged locks into a bright blonde bob, but alas it's not for a Carrie revival but for a new character called Vivienne for a new role in (possibly working title) 'Unfollow The Rules'.

It's official - fringes are having a moment. Jumping on the bangs wagon (get it?), Sofia Vergara debuted a new fringe inspired by the unexpected style icon that is La Chilindrina from the Mexican sitcom El Chavo del Ocho.

Ok, it might just be K-Stew's grown out bleached buzz cut, but we're seriously feeling her new roots and icy tips that remind us of more than a few 90s boyband members. New hair inspo Kirsten?

Although Ciara has kept a relatively low profile since giving birth to daughter Sienna Princess Wilson a few months ago, the singer has recently returned to Instagram with a whole new look. Swapping her ombré blonde locks for waist-length dreads, she captioned the debut post, 'My Post Baby Faux Locs Are Back'.

Ciara last rocked a similar look after giving birth to her son back in 2014. Clearly it's a winner when it comes to no-fuss new mum hair.

Once long, now super short, the Girls actress took to Instagram to reveal her newly cropped locks and posted a picture of her discarded ponytail as well, stating, 'Didn't make it to Locks of Love length but if y'all are considering a cut and have a 10 in pony tail I urge you ✂️ '.

Yes, it's true. The legendary and totally iconic Paris Hilton has transformed her signature Barbie-esque blonde 'do with a chic brunette overhaul. Needless to say we're now doubting everything we once knew and loved (including 'The Simple Life') because we're actually kind of on board with the new, dare we say, Parisian, Paris. In the woman's own words, 'So hot'.

Laters long blonde locks, Amber Heard just transformed into a fiery red head for her role as Mera in the upcoming Aquaman movie. We're feeling serious Poison Ivy vibes...
