Celebrities tend to be style chameleons by nature, changing their looks to suit their latest roles.

This means that, somewhere along the way, the celeb sheds their original look.

And it all seems to start with the hair!

Mandy Moore before and after natural hair

What don’t stars do to their coifs?

Coloring, cutting, straightening, curling celebrities tweak their hair more than most people change their sheets.

It’s like peeking behind the Great and Powerful Oz’s curtain.

Mandy Moore

Close your eyes and picture Mandy Moore.

You’re thinking of Rebecca Pearson fromThis Is Us, aren’t you?

It’s no wonder she never looked back after dying her hair darker for 2002’sA Walk to Remember.

Blake Lively before and after natural hair

There was a real significance to coloring my hair."

For years, Zendaya straightened her naturally curly hair to align with her public image.

“It wasn’t like the hair that girls around me had.

Leighton Meester before and after natural hair

And nobody really knew what to do with my hair.”

But to fans of the iconic teen dramaGossip Girl, Lively will always be Serena van der Woodsen.

It was during her years on the show that Lively first elicited hair lust in, well, everyone.

Gabrielle Union before and after natural hair

She had (and still has) the highly sought-after beachy blonde waves that hair dreams are made of.

In reality, though, little Lively was born with hair considerably darker than her signature blonde shade.

She nearly broke the internet during her pregnancies when she stopped dyeing andrevealed her real roots.

Nicole Kidman before and after natural hair

That isn’t the only hair revelation Lively has hidden up her sleeve.

At one point, it was even super curly just like her daughter James'!

However, Meester’s roots are closer to Lively’s character, and vice versa!

In fact, it was Meester’s willingness to go dark that won herthe iconic part of Blair Waldorf.

Accordingly, Meester had been a blonde through and through when she auditioned forGossip Girl.

That wasn’t going to stop Meester, though.

Emma Stone before and after natural hair

“She came in and she was really funny, and really smart and played vulnerable.

But there was one problem: she was blonde,” series co-creator Josh Schwartz toldVanity Fairin 2017.

So what did Meester do?

Gabrielle Union

In March 2017, Gabrielle Union launched her own haircare line called Flawless.

To provide quality products that would allow women with textured hair “to have great hair days.”

Union opened up to herInstagramfollowers that year about coming to terms with her own natural hair.

Amy Adams before and after natural hair

“It’s been a helluva hair journey.”

Well said, Gab.

However, let it be said that no one regrets the transition more than Kidman.

Katy Perry before and after natural hair

“I wish I had left my hair alone!”

she said, laughing (viaFemale First).

I tortured them to death.

Angela Simmons before and after natural hair

I always say, ‘Don’t ruin the ringlets!'"

Admittedly, it would be killer to see Kidman’s ringlets resurrected.

“I love weaves and wigs and all of that!”

Olivia Wilde before and after natural hair

she gushed toHype Hairin 2015.

“I’ve been wearing my hair natural a lot lately,” Lathan toldHype Hair.

“For me, it’s all about changing it up.

Christina Hendricks before and after natural hair

I’ve been loving that lately.”

If ever there was an exception to this rule, though, it’sLa La LandactressEmma Stone.

You may be thinking, “Wait, she’snota redhead IRL?”

Tyra Banks before and after natural hair

Yet, true story.

Andaccording to Cunningham, Stone feels most like herself when she’s red.

“I forget Emma is not a natural red-head she’s a blonde!

Jennifer Aniston before and after natural hair

She looks like such an authentic red-head with this coloring and her personality!”

“All my girls, including Emma, love it,” Cunningham insisted.

Taraji P. Henson

CanTaraji P. Hensondo no wrong?

Kate Hudson before and after natural hair

TheEmpireactress is essentially on top of the world, and rightly so.

“We have shame when it comes to our hair.

What we’ve been told, ‘Your hair is nappy.’

Keke Palmer before and after natural hair

It’s not nappy, it’s curly.

That’s a curl, that’s a coil.

That’s energy leading up,” she explained during an interview withHuffPost.

Gillian Anderson before and after natural hair

She hopes that in doing so, girls will see their natural hair for what it is.

“It is a crown that God gave you,” she toldHuffPost.

“Our hair defies gravity without any products.

Meghan Markle before and after natural hair

Do you know how powerful that is?

That’s powerful.”

Amy Adams

Not everyone can pull off red hair, but Amy Adams certainly can.

Cardi B with natural hair and treated hair

In fact, she does it so well you probably thought her tresses were natural, right?

In 2004, then-blonde Adams was cast opposite Rob Lowe in the now-defunct TV seriesVegas.

However, there was a hitch.

Michelle Obama with natural hair and treated hair

Another blonde had also been cast and, apparently, two blondes don’t make a right.

Producers insisted one of the actresses would have to change their hair color.

Not that Adams is complaining now.

Billie Eilish with natural hair and colored hair

During a 2016 TimesTalk event, the actress admitted the dye job changed her career.

Katy Perry

No one can accuse Katy Perry of being timid with her style choices.

But Perry’s constant hair overhauls kinda make you wonder where she started.

Ariana Grande with natural hair and styled hair

But back when she was Katy Hudson, the singer still had the lighter hue of youth.

And back in 2011, Simmons really landed on the public’s radar when she revealed her natural hair.

“Nobody was negative,” Simmons said of the big reveal.

Kerry Washington with natural hair and treated hair

“They just didn’t know I had so much hair underneath when I wear weaves.”

But don’t expect to catch Simmons with her natural hair too often.

Per theRun’s Housestar, “I’m the girl who changes my hair all the time.

Laverne Cox with her natural hair and treated hair

My friends just stopped commenting.”

When she first came to Hollywood, though, Wilde was a true blonde.

It wasn’t until she decided to go darker that she had a hair epiphany.

Jennifer Lopez, with natural and treated hair

It’s no wonder Wilde has, for the most part, held onto her adopted brown hue.

Dyeing “so often” hasn’t gone unnoticed either.

Wilde toldCosmoin 2013 that fiance Jason Sudeikis can’t help but tease her about her hot-potato hair color habit.

Christina Hendricks

Can it really be?

Is Joan Holloway naturally… blonde?

As it turns out, Hendricks has always felt the same truth was evident.

She first dyed her hair from blonde to red at the tender age of 10.

There was just something about her… something sparkly!"

The hue has been good to Hendricks over the years.

In 2015, she toldPeopleit helped her book more modeling gigs in her pre-screen days.

Happily, a year later Banks convinced the lingerie company to give her one more chance.

Jennifer Aniston

Jennifer Aniston is nothing if not a hair trendsetter.

First (and, like, obviously) came her iconicFriendshaircut, “The Rachel.”

After that, Aniston segued into her now signature “bronde” hue.

Who among us hasn’t asked our colorist to copy that oh-so enviable caramel color?

Aniston understands the desire for a natural hair do-over, given she long ago abandoned her brunette roots.

After dying her hair dark again for a role, the actress alluded to the swap.

“Work with your own color.

“Freedom,” she simply captionedthe pic.

I just don’t care,” she toldETin 2017.

“People say, ‘Why do black girls perm their hair?

Why do black girls wear weaves?’

The issue, of course, wasn’t with the wig itself.

Her character’s red hair is iconic, you know.

As such, her colorist advised her against returning to Scully’s signature hue.

Plus, if she’s really being honest, Anderson wasn’t a huge fan of the red anyway.

“SOLVED MY OWN CASE!”

“We got curls in the royal palace y’all!!!”

Markle’s hair looks gorgeous both ways, likely a result of how well she cares for it.

It smells like vacation and makes your hair slippery and touchable.”

She even had a ‘do that was dyed specifically to match her Lamborghini, according toRefinery29.

But equally as impressive as those styles is Cardi B’s natural hair, which is full of body.

“Look at my hair.

This is dead-a** my f**king real hair,” she said in the video.

Lemme wash it.

Wow, I’m so proud of myself."

We can see why, Cardi!

That was especially trying during certain times of the year when she couldn’t give her hair a break.

“Because we’d have [to host] parties every day.

“December was a tough hair month.”

However, since leaving the White House, Obama has been rocking her natural hair in public more often.

“Somebody dyed my hair, and they … burnt half of it off.

Now it looks like a mullet,” she toldTMZ.

“That s**t is not on purpose, though.

I’m growing that s**t out.”

you could also see her au natural look in a compilation of herVinevideos.

It’s hard to believe that’s the same person!

“Get a load a dis,” she wrote in the caption.

Who knew she looked so good with her natural hair?

“By the end of 2011, my hair was brittle and breaking off.

My hair does not like relaxers.”

So from that point on, Cox swore off them for life.

Of course, no matter what, she looks incredible!

“I like to maintain a certain sense of fantasy,” the celeb toldGlam Belleza Latina.

“At home, do I have the full hair and makeup?

But I might have the nice dress on.”
