1Kendall Jenner
Snapchat - Kendall JennerLooks like Kylie (and her love of pastel locks) has been rubbing off on her big sis. Yep, Kendall Jenner shared a glimpse of her cool AF new hair on snapchat, and guess what? Her brunette lengths now have flashes of dusty-purple mixed in with 'em. Nice, huh?
Now we know it's highly unlikely that Kendall opted for a permanent colour change, instead her new 'do is probably due to some well-placed pastel extensions. But we're enjoying seeing Kenny with a crazier hair colour...
2Elle Fanning
instagram/ElleFanningElle Fanning has given her blonde lengths a pastel pink (- or as she calls it, dusty?') makeover. The star took to instagram (where else?) to show off her cool new colour and we're loving it.
Upgrading from her typically blonde locks, Elle proved that dreamy pastel pink is the ultimate hair hue for summer.

3Maisie Williams
gettyNow that this season of GOT is over ?, Maisie Williams has decided to switch up her hairstyle with a new colour, and we're feelin' this bold new look. Yep, our favourite Stark girl (sorry Sansa), showcased her newly dyed dark-blue locks at the annual Serpentine Summer Party in London, and she looked... ?
4Rita Ora
Instagram.com/ritaoraRita Ora has worn a rainbow of hair hues but this spearmint blue one is a firm fave. Try it with a weave or wig if you don't want to commit and pair with plenty of fierce eye makeup.

5Lena Dunham
Lena recently debuted her green hair on Instagram (where else?) and although it doesn't exactly scream chic, she somehow manages to pull it off with total ease and we think it looks pretty cool! The Girls star is currently in the UK promoting her new book, and what better way to do it than with new dyed locks? Perfect for Halloween too...
6Kate Hudson
Kate Hudson proves that pink hair can be chic. And if truth be told we've never wanted to dye our hair pink as much as we did when we saw Kate Hudson's new hue. The actress dyed her hair in honour of Breast Cancer Awareness month and she looks seriously good, plus the fact it's for a good cause makes us love it even more.

7Nicole Richie
Does Nicole ever get it wrong? No, we thought not either. She's gone from lilac, to purple, to bright blue and now indigo for autumn, and it's probably our fave colour on her so far. We doubt it's a shade that would suit everybody but Nicole definitely manages to pull it off. We love.
8Jennifer Hudson
Woah. Talk about fierce. J-Hud showed off her ridiculously amazing purple/grey hair and undercut last week and we cannot stop looking at her. Doesn't she look insanely amazing? It's not often we see her with bright coloured hair but doesn't she look amazing? We say she should embrace the colour more often.

9Ashley Tisdale
Ashley Tisdale obviously embraced the fact her wedding is over by dying the ends of her blonde locks. The lavender shade makes a nice change from all the pink that's around and it's making us want to experiment...
10Amber Le Bon
We get plenty of hair inspiration from Amber Le Bon, although we havent quite managed to grow our locks as long as hers just yet. The model often champions the dip-dye and has recently opted for My Little Pony colours. The subtlety of the pastel shades is a look we will definitely be imitating for festivals.

11Hayley Williams
Hayley Williams has been a very busy girl. Before heading to the MTV Movie Awards she was at Nylon and Boss Oranges pool party in California. Her bright hair stood out at both events. Did she get her inspiration from fruit salad sweets? Its certainly the right colour scheme. Looking at the backdrop, it seems like the singer was matching the hosts. We love it on the Paramore star.
12Dakota Fanning
Have you been keeping up with Dakota Fanning's ever-changing locks? We've seen her go from blonde to brunette to blonde again. And now she's gone pink for the second time. My Little Pony hair is still a big hit with celebs. It isn't Dakota's most polished do, but the teenager is entitled to some fun.

13Jade Thirlwall
Little Mixer Jade Thirlwall has added electric blue to the ends of her inky mane. Using Using Schwarzkopf LIVE Colour XXL, the mini Cheryl (just us?) added a kaleidoscopic twist to her glamorous hairstyle, tweeting: "Just dyed me hair 'electric blue' with Live Color XXL Ultra Brights and I absolutely LOOOVVVEEE it!!! :)"
14Perrie Edwards
Oh, how we heart Perrie Edwards' new ombre pink hairstyle. Using Schwarzkopf LIVE Colour XXL, Little Mix took to Twitter to show off their new rainbow hair colours. Perrie ditched her lilac locks, dialling up her look a notch with a fresh-for-spring candy pink colour. The singer tweeted: "Fancied a bit of a change... Nice Ultra brights, shocking pink dip dye! #candyflosshair"

15Nicki Minaj
It looked like Nicki Minaj caught pink fever! She dyed her platinum blonde hair pink on Good Morning America in New York. She paired it with pink eye shadow, pink lipstick, pink nails and a matching pink suit. We could definitely see plenty of Barbie-doll inspiration for this look. What do you think of this pink madness?
16Christina Aguilera
Wow! Christina Aguilera has taken a hair colour risk – she went for rainbow coloured hair at the 40th Anniversary American Music Awards nominations press conference. Hmm, we're still on the fence as to whether we love or loathe her My Little Pony locks - just like we wouldn't wear a rainbow of colours on our face, we're not convinced we'd dip–dye the ends of our hair in a multitude of colours either. Only time will tell whether this look catches on...

17Azealia Banks
Rapper Azealia Banks isnt shy to speak out on Twitter, so were not surprised to see her flaunting emerald green hair colour at Paris Fashion Week. She showed up front row at the Thierry Mugler Spring 2013 show tweeting that her hair looked like the earth and coined the term #earthweave. Was she going for a mermaid-style look, or more the wicked witch in the Wizard of Oz? Well never know...
18Katy Perry
Teenage Dream Katy Perry isn't afraid to dip in and out of extrovert dye jobs and hairstyles! Her bright blue bob definitely turned heads earlier this year, so it comes as no surprise to see that she's moved along the colour spectrum into deep purple. Dramatic, unconventional, vibrant and utterly in keeping with her new 'darker' music sound, Katy has proven once again that she can pull off any hair hue!

19January Jones
Mad Men hottie January Jones is the latest celeb to go for brights with her hair colour. Opting for a few pink streaks to her blonde locks, the star has gone for a candy-floss chic look. We like!
20Dakota Fanning
Twilight starlet Dakota Fanning is the latest celeb to go for brights with her hair colour. Following in Fearne Cotton's candy-coloured footsteps the star has dip-dyed the ends of her blonde locks hot pink. We like! But reckon the star could do with brightening up her makeup to match.
