Hale posted a photo to Instagram of her new semi-permanent hair change, writing, "Pink you very much 🌸 complete Aria vibes." She also noted that hairstylist Kristin Ess used her Kristin Ess Rose Gold Temporary Spray to color her waves, leaving her with a bright-pink hue that'll last a week or two.

Blair—we mean, Leighton—shocked the internet after her hairstylist DJ Quintero posted a photo of her white-blonde hair with the caption, "Having a blonde moment. 🎨" The platinum hue is compliments of iconic colorist Aura Friedman, who worked with Nexxus to lighten Meester's brunette hair to its ethereal white.

Celeb hairstylist Riawna Capri showed off Jackson's choppy waves and peach-pink highlights on her Instagram with the caption, "This is not a filter, this is #PeachyParis looking like a Bali Sunrise #lovethisgirl."

The actress shared a short clip on Instagram in January 2018, revealing a dramatically different hairstyle. Even though this might be a wig, as Lively is currently filming a movie called The Rhythm Section, the short brown style totally suits the usually blonde actress.

Prepare yourself, because frosted tips are making a comeback in 2017—and Kirsten Stewart is leading the charge. The actress is currently growing out her platinum buzz, and the results are gloriously '90s.

The model debuted a super blonde, short bob at the Met Gala.

It hasn't even been an hour, and Selena Gomez's fresh crop has already accrued almost 1 million likes. Can't wait to see it dry.

The singer took her daredevil hair transformation up a notch by debuting her platinum pixie cut on Snapchat.

Selena Gomez's long, dark-brown waves got a summer makeover. The singer showed off her lighter, red-tinted locks while wearing an equally fiery dress on set for a shoot in New York City.

That's one way to alleviate "Summertime Sadness," har har. Leaving LAX on Wednesday, LDR showed off a new sunny blonde shade, which, with her center-parted curtain bangs, drives the whole California-girl thing home.

Emma Stone is the latest celeb to join the throng of celebs that have gone platinum in the recent months. The actress stepped out with a short, shaggy cut and bleach blonde locks—and the resulting look bears a remarkable resemblance to Taylor Swift.

A veritable vet in the art of changing up her hair, the 27-year-old actress "fueled the fire within," by dyeing her choppy lob a new fiery fuchsia shade.

Kimmy is no stranger to serious hair overhauls, but it's been a while since she's made a big change, opting instead for the temporary transformational powers of wigs and extensions. So is the platinum mane she showed off on Snapchat yesterday for real or faux? Only time and additional selfies will tell.

Just the latest proof that perms are back in a big way, the pop goddess stepped out with a head full of fluffy golden blonde curls.

Debuting her new blonder 'do with the Instagram caption "Miami heat," the rapper kissed being a brunette goodbye once and for all.

The mogul is taking the bleach 'do she rocked for her Vogue cover out into the real world. "Bleachella" she captioned her Instagram post. Looking good, Tay Tay.

Stewart has gone blonde before, but never like this. The actress debuted a new platinum dye job and there's no denying it suits her badass disposition.

Emma Roberts loves herself a musical festival beauty moment. So much so in fact that celebrity hairstylist Nikki Lee created a "Desert Rose" hair color—a sunset-perfect bronze—for Roberts "just in time for #Coachella."

One of the perks of being a model is the opportunity to test-drive new hair colors without the commitment. The brunette model showed off a wavy blonde look on Instagram, and while it's only temporary for a photo shoot, we think she should consider going golden full-time.

During a trip to sister Kylie's lip kit factory, Kim unveiled a new ombré 'do on her Snapchat. Her dip-dyed, honey-hued strands are a perfect beauty remix for summer.

Going blonde, going blonde, going blonder! Hale has finally reached peak blonde after weeks of gradual lightening. The Pretty Little Liars actress showed off her cool, ashy hue, courtesy of colorist Kristen Ess.

While her sister has experimented with a variety of hair colors, Ashley Olsen has rarely strayed from her familiar golden strands—until now. The perennial blonde attended a NYFW event debuting a newly darkened mane. Considering the major evolution her personal style has gone through over the years, we're surprised it's taken her this long to trade in those beachy ombré tresses for a more sophisticated hue like this rich chocolatey brown.

You can't even *see* her hair under the habit her character wears, but Agron nonetheless colored her hair brunette to play a young nun in Novitiate.

The Pretty Little Liars star changed things up with a blonder 'do, though from the looks of it, the change is going to be a quick one.

She's lightened up the mid-lengths of her hair down to match her self-deprecating "fashion scarecrow" Instagram caption.

The singer has updated her golden blonde locks to a new but still equally beachy coral hue. It doesn't look like the pink hair thing is going away anytime soon—and Azalea's mermaid-inspired shade is the trend at its best.

Emma Watson has hopped on the bang bandwagon. The actress has updated her classic, polished style with a fresh set of wispy fringe that feels girlish, yet still grown up.

The Girls star has updated her sleek, polished cut with a set of gamine-inspired bangs. Williams debuted her fresh, textured fringe—courtesy of Jennifer Aniston's hairstylist Chris McMillan—on Instagram this week.

There's no stopping the Younger actress, who's done everything short of buzzing her hair this year. This time, she's gone for a soft lavender shade and bendy texture. [In a Minion voice] Soooo pretttyyy.

Biebs is hopping on the pastel strands train, showing off a head of newly lavender locks on Instagram.
