Treatwell Just Revealed The Most Popular Beauty Treatments Of 2019

Carey Mulligan - famous for starring in The Great Gatsby (2013), An Education (2009) and more - has elfin beauty which means she can pull off pretty much any haircut she likes. This sandy pixie crop has got to be our favourite though.

Carey Mulligan made her pixie crop red carpet ready with retro finger curls, taking inspiration from her character Daisy Buchanan in The Great Gatsby. We're not sure we could pull off '20s hair and makeup as well.

Emma Watson's post-Potter haircut is still one of our favourite hair transformations of all time. She told The Metro back in 2010 that the choice to cut her hair was an ode to the end of the Harry Potter era and also signified her desire to establish her own identity, separate from Hermione Granger.

You may know Faye Marsay as The Waif in Game of Thrones, but off-screen she's all modern-day glamour. Her cropped bob is sleek and sophisticated, and her dark eyes and lips increase the drama of her look.

Actress Kate Mara's boyish pixie crop is one of the coolest celebrity haircuts ever. The House of Cards (2013) and The Martian (2015) star has a strong jawline and feminine features which means she can pull off shorter hair.

We also love Kate Mara's slick wet-look take on the pixie hair trend. The extreme side parting makes it dynamic (but we're betting there is a lot of hairspray involved).

For a more laid-back, girl-next-door look, Kate Mara styled her pixie crop with waves and casually-swept fringe. She is our modern-day pixie crop icon.

Actress Ginnifer Goodwin's - known for Walk the Line (2005) and Zootropolis (2016) - rocks an asymmetrical pixie crop hairstyle really well. Her pixie facial features hold the hairstyle on its own, so we bet it takes her roughly a minute to style every morning.

Singer Halsey's 20s-style retro finger-curled pixie crop is sleek and chic, and the pink tinge to the blonde colour adds glamour and drama.

Bond girl Lea Seydoux's short haircut is just on the verge of crossing into bob territory. It's incredibly feminine - just like her - and the bold lip adds drama. We have such a girl-crush on Lea.

Oscar winner Lupita Nyong'o's short quiff hairstyle is absolutely flawless, which suits her beauty and amazing talent as an actress (if you haven't seen her in 12 Years a Slave you're missing out).

Michelle Williams once said that men hate her short hair. According to the Manchester by the Sea actress, the signature style was cut in memory of Heath Ledger: 'I cut it for the one straight man who has ever liked short hair and I wear it in memorial of somebody who really loved it.'

Australian model, singer, DJ and TV presenter Ruby Rose is known for her sexy sleek crop. It's as cool as she is (very), and she plays around with different quiffs, partings, and colour.

Model and Mad Men (2014-2015) star Sola Bamis' short cut is beautiful and oh-so cool. Her gorgeous smile and bold lipstick complement it perfectly.

Amber Rose is famous for her bleached shaved cut, but it is definitely one for the brave. We're not sure she would look as cool if she wore her hair any differently.

Zendaya's super-short crop is worn in retro finger curls to glorious effect. Pair with smoky eyes and strong brows for full Hollywood drama.

Actress Zendaya's boy-cut curtains hairstyle really shouldn't work, but somehow it really does. Wear with conviction - dramatic makeup and statement jewellery - to execute this look well.

Australian actress Elizabeth Debicki - who played Jordan Baker in The Great Gatsby (2013), and has since been in TV shows such as The Night Manager - undoubtedly suits shot hair. The blonde side-swept pixie crop complements her bone structure and delicate facial features.

Known for starring in the Thor films, Jaimie Alexander's short haircut is one of the most copied hairstyles of the year. We love the cool quiff and edgy cropped sides. Oh, and the glasses are the perfect touch.

Kristen Stewart's super-short bleached bob haircut is top of our haircut lust list right now. And we're loving the dirty-blonde roots - they add a coolness to the look (and letting your roots grow out is a great way to save money at the salon).

Vampire Diaries* star Lucy Fry used to have thick long blonde hair, but her slick pixie haircut is oh-so cool. Though, we think her Cara-esque eyebrows are what make this look so awesome.

Spanish actress Paz Vega's voluminous pixie crop is perfect for pulling off statement makeup looks. The OA (2016) and Spanglish (2004) star has pulled off all hair lengths, but with a face like hers it wouldn't be hard to.

Oscar winner Charlize Theron gave her pixie crop a modern feel with blonde highlights, but the small quiff is definitely a glimpse back to boyband the fashion of the Noughties.

In ode to her profession, Anne Hathaway cut her hair short for her all-encompassing role in Les Miserables (2012). At first she hated it, but even she can't deny that the boyish cut actually suits her feminine facial features perfectly.

Dancing with the Stars* pro and Safe Haven actress Julianne Hough rocked short hair in 2014. She looked very chic with it slicked back over to the side.

Actress and dancer Julianne Hough has worn her short hair in an array of styles. Here she has swept her bangs across which frames her face beautifully.

Julianne Hough looks amazing with her short hair waved and textured. She looks beachy but still glamorous.

Frankie Bridge, 1/5 of the girlband The Saturdays, is well-known for going for the ultimate chop. She cut her long brunette hair into a boyish pixie cut with shave sides and full fringe years ago, and we love it. It perfectly complements her delicate and pretty facial features.

Hollywood sensation Jennifer Lawrence has also joined the ranks of A-listers who have experimented with short hair. She styled hers in a boyish quiff at the Oscars in 2014, but styled it with silver jewellery and a red ballgown. The overall effect was so cool.

Jennifer Lawrence looked very girl-next-door with her short hair swept across her face. She made it more Hollywood-glamour by putting highlights through it.

Actress Marion Cotillard channeled her inner Elvis when she styled her short do in a dramatic quiff. So statement - we love it.

Actress Jessica Alba styled her blonde bob in waves for the Hollywood-glamour effect, and she looked very pretty.

Young Jessica Alba looked very Noughties with her poker-straight blonde bob. We're not sure this will be a look she will be revisiting though...

Jessica Alba experimented with her short hairdo, but putting extreme poodle curls for the Marilyn Effect. We much prefer her hair more natural.

Victoria upped her short-hair game again and again. This time her pob was slick-back and glamorous, and her smoky eye makeup added to the drama.

Victoria Beckham is the queen of short hair. Her graduated bob, or should we say 'pob' (posh bob) was the hair trend of the time.

Victoria Beckham's Noughties boyish crop was a dramatic departure from her Spice Girls look - a Hollywood reboot.

Model Agnes Deyn is well-known for her short hair, and for good reason. Her jawline carries short hair really well, and it also looked good bleach blonde.

We think that Oscar-winning actress Halle Berry looks best with short dark hair - it complements her beautiful facial features and elongates her top frame.

Vanessa Hudgens made a dramatic hair transformation in 2011 when she cut her hair into a short crop - far away from her long princess hair in High School Musical.

After her days of being a Disney sweetheart, singer and actress Demi Lovato experimented with short hair, including with colour and lengths. Rock chick chic.

Miley Cyrus seemed to change her personality overnight under the spotlight's glare. The sweet country singer and star of Disney's Hannah Montana had pretty standard teenage hair up until 2012, when she injected some glamour into her look and rocked a balayage bob. In 2013, however, she did a full 180 and debuted a bleach blonde pixie crop. By pairing this staple short mop with provocative and wild outfits she quickly became someone we could not take our eyes off.

When Rihanna cut her hair short she played around with lengths and colours constantly. It was like she had new hair every week.

Rihanna has had tried every hairstyle it seems. Since the days of 'Pon de Replay' back in 2005 she has tried an array of looks and made-over her hair from one extreme to another, sometimes a few times in one year. Although her hairstyles are ephemeral they leave a lasting impression; we adored her bright red 'Only Girl In The World' crop in 2010.

Ri Ri's sleek black crop in 2012 is one of our favourite of her looks.

Scarlett Johansson was another actress who went for the dramatic chop, from long blonde waves to a boyish crop.

Canadian model Coco Rocha is known for her short hair and pixie-like facial features. Here she is rocking an auburn shade and a small quiff.

Model Coco Rocha has worn an array of short hairstyles, and this is by far the most dramatic. The straight, bowl haircut would not be pulled off by most people it's for sure.

Katie Holmes rocked short hair in the Noughties, and with great success. We love this casual side-swept boyish crop and smoky eye combo.

Heroes* actress Hayden Panettiere has also gone for the cop and worn her hair in a crop hairstyle. The swept-back golden looks great with her California girl style.
