The cast of 'The O.C.' and their jaw-dropping before and afters

Let's start with the man who started it all, or 'brought in the stray' if you will. Sandy 'Eyebrows' Cohen is still as handsome as ever, now just with a little salt sprinkled in that pepper hair.

Rowan hasn't attended a public event since 2015 but was last spotted with the chic, blonde lob she became synonymous with in later seasons. 

He may have ditched the grey hoodie and choker combo, but Ben McKenzie still looks like the tough kid from Chino we all know and love. Perhaps just a little less broody.

Adam Brody swapped polos and patterned sweaters for facial hair and a beaded necklace during an appearance in the sitcom Single Parents. We're not sure if this look would be Blair Waldorf-approved.

From The O.C. to The Hills: New Beginnings, Mischa Barton switched faux drama for reality TV in 2019 (same-same though, right?). And while she dabbled as a brunette for a while, she's back to her Marissa Cooper honey hue, only cropped shorter into a shoulder-grazing lob.  

As Summer's character developed, so did Rachel Bilson's chic beauty sense. Look, we know the red lip and blue eyeshadow combo was for a ploy as Wonder Woman in season one, but this sophisticated centre-part pony and sharp brown liner flick shows serious growth.

Trust Julie Cooper to have hardly aged a day. If it weren't for the blonde highlights from the pilot episode, we'd have to do a double-take. All those jogs around the trailer park worked wonders.

Tate Donovan is embracing his greys and honestly, if ours were as even and gorgeous as this, we would too.

Don't get us wrong, Armstrong is as stunning as ever, but we feel a return to the pixie cut of her character wouldn't be a wrong move.

Our favourite (and only) Kiwi cast member has remained unchanged since his days as Caleb.

Whether you hated her bossy attitude or loved her tryst with Ryan, Taylor Townsend had the best hair on set. These days Reeser wears it in a lob, but it's still shiny as hell.

Chris Carmack may have moved on to Greys Anatomy, but his floppy Orange County 'do constantly reminds us where he came from.

Ok, so we know this pic couldn't be more 2020, but it was the only one that showed off Lucio's new pixie cut. Ain't it cute?!

When Kaitlin Cooper came home from boarding school all grown up, it was all about super-straight hair and statement eyeliner. And it seems Holland held tight to the liner, adding some smokey shadow to soften. We also love her most recent chin-length chop.

Choosing a favourite brother in the show was a no-brainer but damn, Marshall-Green is making his case in 2021.

Noooo! RIP to Zach's adorable mane of hair. Sorry Cassidy, please bring it back. Think of the '00s nostalgia.

Johnny's long hair lives on, though Donowho prefers a moody wet-look mop over fluffy, flicked-out ends.  

Kevin Volchok: responsible for killing Marissa Cooper. Cam Gigandet: responsible for piercing our hearts with those blue eyes.

What's edgier: Alex's purple streak or Olivia Wilde's floating crease smokey eye? We choose whatever Harry chooses.

You can change your hair all you want Handley but we'll NEVER FORGET. 

Maybe it's the pink turtleneck or maybe it's the lighting, either way Rawat got younger and we want ANSWERS.

We used to think Summer's *enlightened* University pal Ché was world's away from a Guardians of the Galaxy Chris Pratt. However, his recent moustache is bringing us right back to that baggy-capped relationship decoy. 

Ok, seriously, how many love interests did Ryan Atwood have? Nikki Reed may have been a fleeting one, but we maintain it set her up for Twilight.

Before she magically grew up five years in the space of two seasons, Kaitlin Cooper was played by none other than Shailene Woodley.
