Eyebrows serve two main purposes,according to experts.

They also help filter light, which also serves as eye protection.

Eyebrows also play a significant role in communication.

Kylie Jenner

We all recognize a furrowed brow to indicate displeasure or raised brows to signify surprise.

But, beyond just helping us demonstrate and understand emotion, eyebrows are useful for facial recognition.

Brows canliterallychange how we see people.

Drew Barrymore before and after eyebrows

Here are some of the most noteworthy transformations to date.

Nevertheless, her eyebrows may have had the most impact.

By the time “Tommy Boy” premiered in 1995, the actress' brows were pencil-thin.

Lucy Hale before and after eyebrows

Just asBarrymore’s rebellious yearsare long behind her, her itty-bitty brows are also a thing of the past.

“The eyebrows tho,” wrote one commenter.

Another questioned why the girls would pluck their brows at that age.

Kim Kardashian before and after eyebrows

The early 2000s were a different time that’s for sure but Haledoesagree with naysayers.

“I overplucked mine and they just looked crazy,” she said in an interview withPeople.

That’s certainly not the case anymore.

Jennifer Aniston before and after eyebrows

She admitted toPeoplethat, despite all the plucking, she’s always had very full eyebrows.

Surprisingly, she still does her brows herself.

“I just get a little nervous when people venture to touch them,” she explained.

Megan Fox before and after eyebrows

Well, whatever she’s doing, it’s working!

Kim Kardashian

Kim Kardashian has gone through many transformations over the years.

In the late ’90s, Kardashian embraced much smaller and tightly shaped eyebrows.

Gwen Stefani before and after eyebrows

In athrowback Instagram photoshared by Kris Jenner, Kardashian is hardly recognizable with her former arches.

Kardashian herself commented on the photo writing, “I look horrendous!

I was obsessed with Drew Barrymore and her thin eyebrows!”

Paris Hilton before and after eyebrows

Both women are likely thankful that they’ve come to embrace fuller brows.

That’s not to say it’s easy to go from thin to thick brows.

Jennifer Aniston

When Jennifer Aniston was busy starring inFriendsas Rachel in the 2000s, her haircut gainedmajorattention.

Angelina Jolie before and after eyebrows

“That was kind of cringe-y for me,” she admitted toGlamour.

But the iconic haircut isn’t the only thing Aniston regrets from that time.

In an interview withElle, Aniston said she will never again “bleach out [her] eyebrows.”

Kylie Jenner before and after eyebrows

She further explained, “It was a real look in the 90s.”

At the time, Aniston got her brows bleached for her very firstCosmopolitancover shoot.

Thankfully, Aniston’s eyebrows have recovered from their days of being over-plucked and lightened.

Lena Dunham eyebrows before and after

Megan Fox

Megan Fox and #browgoals are essentially synonymous.

This wasn’t always the case, however.

Shaping brows is not a one-fits-all solution, Crooks explained toRefinery29.

Lady Gage eyebrows before and after

“Brows for me fall into one of three categories: arch, arc, or straight.

Megan Fox has a classic arch,” she said.

Something would be off.

Cara Delevingne eyebrows before and after

Gwen Stefani

Gwen Stefani has always had anepicsense of style.

She seems to be one who is much more likely to set trends than follow them.

Yet and still, she became victim tothe tiny brow.

Rita Ora eyebrows before and after

With a bindi and studs framing her eyes, her thin arched painted-on eyebrows were on full display.

In 1999, Stefani’s brows seemed to get even thinner.

“I had chemical burns,” she said, “But I survived!

Bella Hadid eyebrows before and after

I do have a scar, though.”

Scars and all, Stefani achieved brow-goal status in 2015 and has been rocking thick brows ever since.

Paris Hilton

Can you even think about the early 2000s without remembering Paris Hilton?

Jennifer Lopez eyebrows before and after

There were no limits to the heiress' style in those days.

Fromtracksuits to tiaras, Hilton was obviously not afraid of trying and creating new trends.

“It was the style back then,” she added.

Madonna eyebrows 2013/2017

She also admitted that she even gets her eyebrows dyed.

“Otherwise they look sparse,” she told the magazine.

Kylie Jenner

For most of her teen years, Kylie Jenner favored thin brows.

In 2014, however, Jenner hosted theMuchMusic Video Awardsand her brows quite literally began to take shape.

With long lashes and expertly defined brows, Jenner was starting her evolution to Brow Queen.

Much like her half-sister Kim Kardashian, Jenner has a brow artist to help her out.

Bryant explained that fuller brows give off a youthful appearance.

“Thinned out brows age women,” she added.

“What the f*** is wrong with your eyebrows?”

Dunham recalled one decidedly popular boy asking her.

Lady Gaga

Is there a look Lady Gagahasn’ttried?

In the past, Gaga’s standby look was bleached brows.

Gaga sat down withVogueat the Marc Jacobs Fall 2016 runway show and discussed her eyebrow routine.

“They’re more versatile for a beauty look.

you’re able to draw [your eyebrows] any way you want when they’re bleached.”

They may be more versatile, but daily bleaching is not generally advised.

Just because it worked for Gaga doesn’t mean it’ll work for us.Sigh.

Cara Delevingne

To say Cara Delevingne has epic brows would be an understatement.

Nevertheless, they weren’t always the big and bold brows you now know and love.

In years past, the star had noticeablytamer and lighter eyebrows.

But they’ve always been thick.

The star admitted toInStylethat she once wanted less bushy brows.

Because of that, she said she would “attempt to tweeze them down.”

Of course, we’re allobsessedwith her iconic brows these days which is something the star thinks is nice.

“It’s really sweet; I’m flattered,” Delevingne toldByrdie.

There’s enough room on this planet for big and small brows after all, right?

Rita Ora

Remember when Rita Ora bleached her eyebrows?

Well, the internet never forgets.

“You’ve got to commit nowadays guys!”

Ora said of her adventurous look.

She further admitted that the process “really burnt.

“Eek, that’s never a good sign.

“I don’t know if I’m going to get my eyebrows back,” she opined.

“They don’t fall out like hair do they?”

Thankfully for Ora, she seems to have gotten her brows back.

While bleaching them may have been fun at the time, her updated brows are truly stellar.

And, surprisingly, they’re not very high-maintenance either.

“A brown mascara,” she added.

Hey, whatever works.

In doing so, her brows have only given her a more distinctive look.

“I’ve always had really thin brows, I got them from my dad.”

“Fake it till you make it, I guess,” she told the publication.

You know, that style where the beginning of the brow was as thick as the tail?

Sure, it wasn’t as terrible asthe ’90s brow, but still.

Why did we ever thinkeitherwas a good look?

These days, Lopez’s brows vary in thickness appropriately.

They’re bold without being distracting, and, more importantly, they work well with her face shape.

The star revealed her favorite brow product in an interview withInStyle.

As of late 2018, the celeb stands by the Iconic London Sculpt and Boost Eyebrow Cushion.

Madonna

Madonna’s eyebrows have gone throughalmostas many changes as the Queen of Pop herself.

In the ’80s,she led the no-pluck movementand let her brows do their own thing.

By the ’90s, though, the singer experimented with super-thin brows just like all the rest of us.

Madonna would end up sticking with the itty bitty brows for a long time.

According toUs Weekly, Madonna now opts for the same procedure asLena Dunham: microblading.

Although this brow trend has gotten increasingly popular, we all know how styles change.

Despite being a tattooing technique, microblading is only semi-permanent.
