40 celebrity hair transformations that'll have you running to the salon

From drastic chops to the boldest hair dyes... here are all the most jawdropping celebrity hair transformations of the year.

1. 

   1. Katherine Langford

   Katherine Langford debuted her new flowing red hair on Instagram. The young actress is known for her dark brown hair in Netflix's '13 Reasons Why', though she did go blonde for the film 'Spontaneous'. This time, many are guessing Katherine has gone red for her role in Netflix's 'Cursed', where she plays Nimue (aka the Lady of The Lake).

2. 

   2. Ariana Grande

   Ariana Grande has debuted a new shoulder length haircut on Instagram. After working her signature ponytail for years, the 'thank u, next' singer can now be seen sporting her natural, brunette hair and it's gorgeous. Whether or not Ariana will still wear a ponytail for performances and videos still is yet to be seen but we're loving this new look regardless.

3. 

   3. Joey King

   She JUST died her hair blonde but that wasn't enough because the 'Kissing Booth' star just dipped her locks in some bright blue dye and now she's rocking blue hair! No word from Joey yet on whether or not it's for a role or if it's just for fun but we're not gonna lie... we kinda LOVE it. We might end up doing the same this weekend.

4. 

   4. Lana Condor

   Kiss goodbye to Lara Jean Covey's long locks because Lana Condor just went for the biggest chop EVER! Yep, Lana is now rocking an adorable above-the-shoulder cut and we're about three seconds away from copying her. Writing on Instagram, Lana revealed the reason behind the drastic new look: "I’m shooting season 1 of @deadlyclasssyfy and they chopped off all my hair, and subsequently also saved me so much money now on shampoo and conditioner." OBSESSED!

5. 

   5. Joey King

   Elle Evans is blonde now! Yep, 'The Kissing Booth' star Joey King has ditched her brunette locks and has gone blonde - with some brand new bangs too. Joey shared the snap on Instagram with the caption "Oh shit, I'm blonde now," and by the sounds of things, she's just as shook as we are.

7. 

   6. Dylan Sprouse

   PSA: Both Sprouse twins how have short hair! Yep, after years of sporting shoulder length locks, Dylan has decided to cut off all his hair in favour of a new look. Honestly, the long hair was a look but this? WE STAN.

8. 

   7. Lucy Hale

   She's back! After spending years rocking that adorable and chic brunette bob, Lucy Hale is back on the blonde train! Is there any hair colour this queen can't pull off?

9. 

   8. Leighton Meester

   Good morning, Upper East Siders, Gossip Girl here. It looks like B has finally ditched those brunette locks that have been holding her back and embraced her inner blonde but do blondes really have more fun? Yep, ya girl Leighton Meester has gone BLEACH BLONDE in her boldest look yet and she looks incredible. Kind of got us thinking about pulling a Little J and stealing her aesthetic...

10. 

    9. KJ Apa

    Looks like school's out and summer is on for KJ Apa already! Ya boi Archie Andrews has ditched his red locks (he dyes them frequently for 'Riverdale') and has gone back to his natural dark hair while he shoots his new movie 'The Last Summer'. DOn't worry though, the red hair will be back in a few months. 'Riverdale' hasn't officially been renewed yet but it's an odds-on lock to return in the fall.

11. 

    10. Katherine Langford

    We're used to seeing Katherine Langford with her signature brown tresses, but the '13 Reasons Why' star is apparently mixing things up with a stark blonde look. Fans of her brown hair can relax, though. Katherine's new peroxide do appears to be a wig for her upcoming film, "Spontaneous". She lowkey pulls it off though, right?! Copyright © 2018 BACKGRID UK

13. 

    11. Selena Gomez

    No, it's not a wig - Selena has actually taken the plunge and gone FULL blonde! Queen of whispers Selena Gomez debuted her brand new look on the red carpet at the 2017 AMAs and she looks absolutely incredible. Selena also shared pictures of her blonde locks on Instagram with the caption "so i am blonde now" ...And we are obsessed now.

14. 

    12. Dove Cameron

    The good sis Dove Cameron is known for having the most gorgeous long icy blonde locks but it looks like she has FINALLY gone for the chop. Dove has rocked short bob style lewks in the past but she later revealed they were wigs - has she really gone and done the damn thing this time? It’d make sense at least, considering there’s a role currently up for grabs that requires short blonde bob-length hair… Sabrina the Teenage Witch, anyone?

15. 

    13. Matty Healy

    The 1975 frontman has been spotted on Instagram this week sporting a buzzcut as he prepares to record the band's third album. We do miss his Sideshow Bob era but apparently he's in LA so maybe this is how he copes in the heat?

16. 

    14. Alexander Skarsgård

    The internet has absolutely LOST IT over Alexander Skarsgård's newly shaved head and we can't decide whether to laugh or cry. Alexander apparently took the plunge and shaved 3/4 of his hair for his new film role in The Hummingbird Project, but all we can see is an unintentional Prince William Halloween costume. Literally dying.

17. 

    15. Millie Bobby Brown

    We didn't think Millie could get any cooler than she already is but... we guess she just did and ended the rest of us in the process. Walking the carpet at the Stranger Things 2 premiere, Millie added some subtle hair extensions to her short locks and looks almost unrecognisable! We wonder if she'll ever grow it back to the length it was before she shaved it all off?

19. 

    16. Natalia Dyer

    Oh, we almost didn't notice ya there, Nancy Wheeler. Just one week ahead of the release of Stranger Things 2, Natalia showed off her freshly dyed locks on social media and she looks SO different! And as for that aesthetic with those new bangs? We have decided to stan.

20. 

    17. Bella Thorne

    SHE’S BACK ON HER BULLSH*T. Bella Thorne has switched up her hair *again* and this time, she’s gone shorter than ever. After teasing her new cut on Twitter, it seemed like she was kinda forced into chopping off her locks. Bella shared a picture of her hair in what looks like a massive matted knot but maybe it was for the best, ‘cause she looks fierce AF with her new shoulder length lob. Now we sit and wait for the next colour change… or inevitable addition of her ol' trusty hair extensions.

21. 

    18. Dove Cameron

    Dove Cameron, Queen of icy blonde locks and the occasional purple wig, just gave us a glimpse into an alternate reality where she's a fierce brunette and she actually looks unrecognisable. Of course, Dove's new locks are fake (it's a wig, you guys) so don't worry, she's still serving that Sabrina the Teenage Witch aesthetic.

22. 

    19. Zayn Malik

    Your MCM no longer has any hair. Yep, Zayn is bald. King of pink, green, blonde and his natural dark hair appeared on his mum's Instagram showing off his brand new shaved head in a snap alongside girlfriend Gigi and to be honest, he kind of slays the look! So whaddya reckon? Zayn with his iconic locks, or without...?

23. 

    20. Troye Sivan

    We don't mean to alarm you but precious baby Troye has just evolved into his final and purest form and the world is shook. Troye, who has been (kinda) busy working on his second album took to Twitter (and Instagram) to show his freshly dyed platinum blonde locks. We don't know about you but we've already forgotten what he looked like as a brunette. May the #BlondTroye era never end.

25. 

    21. Bella Thorne

    For what might be the 73rd time this year, Bella has dyed her hair again. After going blonde for literally less than a month, Bella enlisted the help of her sister Dani to dye her hair the brightest shade of neon pink you could ever hope to see in your life and she documented the entire thing on Snapchat. Not gonna lie though, we love this way more than the blue. In fact, is there any colour that Bella can't rock?

26. 

    22. Billie Lourd

    Stop what you're doing... Billie Lourd has just dyed her long blonde locks an icy shade of grey for her role in 'American Horror Story' and it looks majestic. She captioned the snap #WinterIsComing, which means she’s either taking advantage of her new Targaryen aesthetic or… she’s about to cause pure devastation on AHS S7. Billie’s new shade might also be hinting at Ryan Murphy’s 'Red, white and blue’ clue on Instagram. We’ve already seen (maybe) Evan Peters’ blue hair so who will be going red?

27. 

    23. Bella Thorne

    She's ditched the blue and she's gone... blonde? Bella Thorne, Queen of unexpected hair dye, just stripped her infamous blue locks of their colour and has gone back to basics with her freshly dyed locks. She documented the whole ordeal on Snapchat complete with mid-session breakdown over the "ugly" shade of mint that her hair had ended up and shared a snap of her almost WHITE hair. After a quick touch up, she's almost back to her natural strawberry blonde and it looks AMAZINGGGGG. #Obsessed

28. 

    24. Selena Gomez

    Did Selena take inspiration from Hannah Baker's 'New hair, hu dis' haircut in '13 Reasons Why'? 'Cause she's just cut off her locks and it is EVERYTHING! Selena used to rock a much more stylised bob back in the Wizards of Waverly Place days of course but this is almost definitely her shortest style yet. Is it a wig? Maybe - but she looks AMAZING either way.

29. 

    25. Katy Perry

    Katy Perry has been back at it again with the scissors and this time, she's gone full Bieber. Weeks after going from messy blonde bob to dramatic pixie cut, she stepped up her hair game by going all in with this platinum buzzcut.

31. 

    26. Halsey

    Perfectly coinciding with the release of her new single Now Or Never, Halsey went from blonde right back to one of her signature shades. And fam, it's literally dripping like a saturated sunrise.

32. 

    27. Kristen Stewart

    Kristen Stewart stepped out on the red carpet for a screening of her new movie Personal Shopper with literally no hair and the internet went wild for it - long gone are her signature brown shoulder length locks. Can't believe she didn't do this sooner, tbh! #Fierce

33. 

    28. Zoe Kravitz

    New hair, who dis? Zoe kissed goodbye to her signature braids and embraced the hottest look of the season - the pixie cut.

34. 

    29. Cara Delevingne

    Cara Delevingne took a few inches off her stylish lob and went for a silky Malfoy-esque white hue for her new look. Cara later said she made the drastic change before she has to shave her entire head for a film role.

35. 

    30. Katy Perry

    Long gone is that raven-haired Katy Perry we used to know. Please welcome to the stage... Mile- Oh, it's brand new blonde Pixie cut Katy Perry! Her inspiration? Scarlett Johansson, of course!

36. 

    31. Lucy Hale

    Lucy Hale went from short... TO SHORTER. Finishing just in line with her jawline, Lucy's new asymmetrical look is already at the top of our wanted list.

37. 

    32. Emma Roberts

    Scream Queen Emma Roberts and expert at having good hair switched up her ginger locks and went for a gorgeous brown hue - or, as her stylist is called it ~smokey quartz~. Ooooooh.

38. 

    33. Amandla Stenberg

    Amandla had to shave off her gorgeous natural curls for a film role but the gag is, she looks incredible before AND after. When the film wrapped, she dyed it blonde and we've been obsessed ever since.

39. 

    34. Bella Thorne

    After her dramatic watermelon look, Bella decided to switch it up and go full blue. What can we say, it's low-key her best colour yet.

40. 

    35. Carly Rae Jepsen

    Queen of blonde pixie cuts, Carly Rae Jepsen unveiled her gorgeous new hairstyle at an Ice Hockey game - lol, Canada! Now, she looks every inch the bubblegum pop Queen she is.

41. 

    36. Selena Gomez

    Famous for having the most glamorous long dark waves, Selena Gomez pulled the New Year New Me card in January while working on a secret project. Say hello to long bob Selena!

42. 

    37. Ashley Benson

    Nothing like a little dash of pink hair dye to help ring in your birthday is there? Ashley went from her signature blonde to a bright shade of pink after wrapping Pretty Little Liars and we're obsessed.

43. 

    38. Bella Thorne

    We'll say this... No one can EVER accuse Bella Thorne of being boring! Bella and her sister Dani decided to brighten up their lives by dying their hair the most insane shades of red and lime green. #InstagramMoment

44. 

    39. Hayley Williams

    After going Steal My Sunshine yellow and Riot orange, Hayley settled down with this ethereal milky silver colour. SPOILER ALERT: This might be our favourite Hayley look of all time.

45. 

    40. Camila Mendes

    Veronica Lodge is dead! Yep, 'Riverdale' star Camila Mendes has swapped her trademark inky black tresses for a much-lighter brunette shade – just in time for summer too. Camilla also debuted a slightly shorter 'do with chopper layers. The whole hair transformation process took seven hours to complete. So, beauty is in fact pain (and an entire day at the salon).
