She doesn’t just change her hair. She kills off the old version of herself. Honestly, if you’ve followed the Kristen Stewart haircut trajectory from the 2008 Twilight era to right now in early 2026, you know it’s not just about a trim. It’s a full-on identity shift. Most people see a celebrity with a "edgy" look and think it’s a PR stunt or a stylist’s whim. With Stewart, it’s closer to a ritual.
We’ve seen the long, chocolate-brown waves of Bella Swan vanish, replaced by jagged mullets, peroxide buzz cuts, and most recently, a series of experimental undercuts that make "mainstream" beauty standards look totally boring. As of late 2025 and moving into this year, she’s been leaning heavily into a grunge renaissance.
The 2025 Undercut: Why It Actually Changed Everything
In November 2025, Stewart showed up to the Governors Awards with something that looked like a glitch in the Matrix. Her longtime hair collaborator, Adir Abergel, didn't just give her a standard undercut. He basically sculpted her head. The bottom half was buzzed nearly to the skin, while the top remained long and glossy, often pulled into a sharp, "snatched" ponytail.

This wasn't just "short hair." It was a graphic statement. By the time she hit New York for a The Chronology of Water screening a few weeks later, she’d shifted the vibe again. She was rocking what some called a "side-shave illusion." Instead of the nape being the focus, she had the right side of her head buzzed, making it look like her hair was tucked behind her ear—except the hair was just... gone.
Why this specific cut matters right now:
- It defies the "clean girl" aesthetic that dominated the early 2020s.
- It’s designed to look different depending on the camera angle.
- It pairs "masculine" barbering with "feminine" length in a way that feels very 2026.
People always ask: "Can I pull that off?" The answer is usually no, unless you have her bone structure. But that’s the point. Stewart uses her hair to highlight her face, not to hide behind it.
From Neon Pink to "Back to My Roots"
If you blinked during the summer of 2025, you missed the Neon Pink phase. Around July, she was spotted in Los Angeles with a DIY-looking, super-saturated pink hue. It wasn't the "pastel princess" pink you see on Instagram. It was neon. It was loud. It looked like she did it in a bathroom sink, and that’s exactly why it worked.
But by October 2025, she’d pivoted back to her natural brunette for the BFI London Film Festival. This wasn't a retreat to safety, though. She added choppy baby bangs. These aren't the soft, wispy bangs your aunt gets. They are blunt, micro-fringe pieces that sit way above the eyebrow.
The Technical Side: How Adir Abergel Does It
You can’t talk about the Kristen Stewart haircut without talking about Abergel. He’s the architect behind the "controlled mess." He’s gone on record saying he uses unconventional tools—like string hair elastics from fabric stores—to get that specific tension in her updos.
For the texture, it’s rarely just "air-dried." He often uses Virtue Labs products, specifically the Healing Oil and the Restorative Treatment Mask. The secret to her 2026 look is the contrast between healthy, shiny hair on top and the raw, buzzed texture underneath. If you’re trying to replicate this at home, don't just grab a buzzer. You need a stylist who understands "head shape mapping." If the line of the undercut is off by even a few millimeters, the whole "grunge" look just turns into a bad DIY job.

The Mullet History: A Quick Refresher
Before the 2025/2026 undercut era, we had the mullet years. Stewart was one of the first A-listers to reclaim the mullet before it became a TikTok trend.
- The "Joan Jett" Mullet (2010): Very shaggy, very black, very The Runaways.
- The Ombre Mullet (2017): This was the "grown-out buzz cut" look. It had frosted tips that looked like a 90s boy band member gone rogue.
- The Muted Copper Mullet (2024): A softer, "cowboy copper" version that proved she could do "pretty" while still keeping the edge.
Common Misconceptions About Her Style
A lot of people think she hates her hair because she’s always messing with it. Actually, she’s said in interviews that long hair feels like a "character" on her body. When it’s long, she moves differently. When it’s buzzed, she feels more like herself.

Another myth? That she doesn't use products. Her hair looks "lived-in," but it takes work to make hair look that specific kind of "dirty-clean." It involves a lot of dry shampoo and very specific placement of pomade to get those "piecey" ends without looking greasy.
How to Ask for the "Stewart Look" Without Regretting It
If you’re heading to the salon to chase the latest Kristen Stewart haircut, you need to be specific. Don't just show a picture of her at the Governors Awards and say "this."
- Ask for a "disconnected" undercut. This means the long hair and the buzzed hair don't blend.
- Specify the "micro-fringe." If you want those baby bangs, tell your stylist you want them at least an inch above the brow.
- Don't over-process. If you’re going from dark to platinum like she did for Spencer or Underwater, do it in stages. Stewart’s hair is resilient, but yours might not be.
Actionable Steps for Your Next Salon Visit
- Check your hairline. Undercuts look best on people without a lot of cowlicks at the nape.
- Invest in a high-quality hair oil. To get her 2026 shine, you need something like the Virtue Healing Oil to keep the "long" parts looking intentional.
- Commit to the maintenance. A buzz cut or an undercut needs a touch-up every 3-4 weeks. If you let it grow out, you hit the "awkward phase" fast.
The reality is that Kristen Stewart’s hair works because she doesn't care if you like it. That’s the "actionable insight" here. The best haircut isn't the one that's trending—it's the one that makes you walk into a room differently. Whether it's a neon pink bun or a razor-sharp undercut, the goal is to look like you own the style, rather than the style owning you.
