After seeing Chloe Moretz's new dark 'do at this year's Teen Choice Awards, we've ben inspired to find the best (and worst) celebrity dye jobs. Thinking of hitting the bottle? We're talking about hair dye, obvs, not beer! If you fancy a colour change, take a look through our gallery first and steal inspiration from the stars. It's what they're there for...
Before she crossed over to the follicle dark side CGM rocked a honey blonde 'do.
It's hard to believe KP is a natural blonde when she looks this good with raven locks!
Well, she is the voice of Smurfette so blue is an obvious hair choice for Perry.
Katy was one of the first to kick off the pastel hair craze with this washed-out pink 'do.
Corkscrew curls and wine-red dye to go with her red outfit. Rihanna's outfit coordination knows no bounds.
One of our fave ever Rihanna looks. The star looked incredible at this year's Grammy Awards with her glossy ombre waves.
Caz-Flack ditched the bleach for a short time earlier this year, embracing a rich brunette shade.
But it wasn't long before she was back on the (bleach) bottle. If we're totally honest with ourselves Caroline Flack - dip dye is like fish 'n' chips with the vinegar.
Johnny Depp's squeeze Amber Heard is one of the lucky few who look incredible with every hair colour.
See! What did we tell you? Amber's ice-cool platinum 'do and red lips are so Hollywood it hurts.
Remember when Blake Lively went auburn? Yeah, we weren't sure either...
That's better! Blake, please don't mess with your long, blonde locks again. Your hair is just too fabulous the way it is.
Recognise Blake's Gossip Girl buddy? We didn't know Leighton Meester used to be a blondie! We sort of wish we still didn't know.
Leighton looks best with a sharp glossy brunette bob. Her light brown shade perfectly complements Meester's tanned olive skin.
Pre-babies, Lily Allen was a wild thang with a penchant for bleach and uber-bright dye.
Lily's usual hair colour is a super glossy dark brown, suiting her creamy skintone perfectly.
When Tulisa hit the bleach for her court appearance last year we let out an unhappy squeal. The overall colour was uneven and dull adn did nothing for the tanned star.
Her sultry dark 'do was a hit when Tulisa took over from Cheryl Cole on the X Factor. Way more flattering than the dingy blonde dye job.
Jennifer Lawrence's Hunger Games noir was draining on the pretty star.
Whe she dyed her hair a flattering honey with sunkissed-style 'lights we cheered. What a difference a salon appointment makes!
Twilight's Ashley Greene looks fab with uber-dark hair and...
...and hot with fiery auburn locks. And she got to work with Robert Pattinson. Lucky lass.
She's one of the cutest actresses around, regularly hooks up with Ryan Gosling on-screen and is loved-up with Andrew Garfield on-and-off-screen. And if that wasn't luck enough, she also looks amazing as a blonde.
And as a redhead! Emma Stone really does have it all, right?
How much did Emma Stone look like a young Kara Tointon back when she was a brunette?!
We much preferred Dakota Fanning's pale blonde look to her plain brunette style. Need reminding?
Yep, all of a sudden we're just not that into her. Soz, Dakota. Stick to the bleach next time.
Miley Cyrus made our jaws drop when she first stepped out with her peroxide crop.
Is that really the same person?! Yep, pre-Pilates and grillz Miley enjoying walking on the dark side via her hair.
Are you a fan of The O.C.'s Mischa Barton with golden waves?
Or rich, dark curls?
Or does Mischa Barton's hipster bleach 'do with grown-out roots do it for you?
