Everyone knows the blonde. It’s basically been Sydney Sweeney’s calling card since Euphoria exploded onto our screens. That bright, California-cool honey hue helped turn Cassie Howard into a cultural icon, and for a long time, it seemed like Sydney wasn't going to let it go. But lately, things have changed. If you’ve been paying attention to her recent red carpets or film trailers, you’ve probably noticed the Sydney Sweeney brunette hair shift. It isn't just a quick "I'm bored" salon visit. It’s actually a return to her roots—literally.
Believe it or not, the actress is a natural brunette.
She spent years in Hollywood trying to make it with her natural shade, but the roles didn't start flooding in until she reached for the bleach. It’s a classic, slightly frustrating industry trope. Sydney herself has joked about how she felt like a "science experiment" for her stylists, but the truth is deeper. She’s finally at a point in her career where she doesn't need the "blonde bombshell" tag to get in the room.
The Truth About Her Natural Color
Most people assume Sydney is a natural blonde because she wears it so well. Honestly, though, she spent her childhood in Washington state with hair that leaned much darker—even strawberry-tinged at one point. In her teens, it settled into a solid brown.
She once told Times of India that "no one really knew me as brunette Syd." She admitted that she didn't book as many jobs when she was rocking her natural color. That’s a wild thought considering her talent, but it speaks to how much Hollywood relies on a "look." When Everything Sucks and then Euphoria came along, the blonde became her brand.
But the damage was real.

Constant bleaching for years takes a toll on anyone's scalp. By the time she was done with certain press tours, her hair was, in her own words, "fried." She described it as feeling like cotton candy in the shower. Not exactly the glamorous life you'd imagine. This led to a period where she had to lean heavily on wigs—like that striking black bob at the 2024 Met Gala—to give her real strands a break.
Why She Went Dark for "Immaculate" and "Eden"
If you saw the horror flick Immaculate, you saw a version of Sydney that felt much more raw. She played a nun, so the glitz had to go. The Sydney Sweeney brunette hair we saw there was stripped back and practical.
Then came Eden.
In this survival thriller directed by Ron Howard, Sydney plays Margret Wittmer, a real-life settler on a Galápagos island in the 1930s. You can’t exactly maintain a platinum balayage while fighting for survival in the brush. Her hair in the film is a shorter, textured brunette that makes her look like a completely different person. It's moody. It's grounded.
She also shocked everyone with a curly brunette mullet for her role as boxer Christy Martin. It was a massive physical transformation that involved gaining muscle and ditching the "pretty girl" aesthetic entirely. Seeing her in that dark, 90s-style cut made it clear: she’s done playing it safe with her image.

Getting the Look: "Dark Suede Blonde" vs. True Brunette
If you’re looking at her 2025 and 2026 appearances and thinking, "Wait, is that brown or just really dark blonde?" you aren't alone. Her colorist, Jacob Schwartz, coined a specific term for the transition: Dark Suede Blonde.
It’s the ultimate "quiet luxury" hair color.
- The Base: A deep, mushroom-toned brown that looks velvety.
- The Highlights: Super fine, almost invisible ribbons of gold that catch the light.
- The Maintenance: This is the best part—it uses a shadow root, so you don't have to hit the salon every three weeks when your natural hair grows in.
Basically, it's a bridge. It allows her to keep some of that "light" around her face so she doesn't feel washed out, but it lets her natural brunette health take center stage. For anyone who has bleached their hair to death, this is the holy grail of recovery colors.
The "Coco" Controversy
You can't talk about her hair without mentioning the drama. Her longtime stylist, Glen "Coco" Oropeza, is the architect behind a lot of these shifts. In late 2025, things got spicy on social media when critics claimed her hair looked "stiff" or like a bad wig during a Tonight Show appearance.
Coco didn't hold back.

He jumped into the comments to defend the look, confirming it was her real hair and calling out the "tired" narratives people try to spin about her team. It’s rare to see a stylist get that defensive, but it shows how much work goes into these transitions. Moving from a bleached-out blonde to a healthy, shiny brunette isn't an overnight process. It’s a marathon of masks, oils, and "science experiments."
How to Handle Your Own Blonde-to-Brunette Shift
Thinking about following the Sydney Sweeney brunette hair blueprint? Don't just buy a box of dark dye. If you put dark brown over bleached blonde, your hair will probably turn a weird swampy green. Seriously.
You have to "fill" the hair first. This means putting the red and orange pigments back into the hair that the bleach stripped away. Only then can you layer the chocolate or "suede" tones on top.
Actionable Next Steps for Your Hair Transition:
- Ask for a "Tonal Fill": If you’re going from light to dark, tell your stylist you want a two-step process to avoid the color looking flat or muddy.
- Incorporate Bond Builders: Sydney specifically mentioned using Olaplex and Kérastase masks. If you've been bleaching, you need to repair the internal structure before the new color will even "stick."
- The 20% Rule: If you're nervous, don't go jet black. Start by lowering the brightness of your blonde by 20% using lowlights. It’s how the "Dark Suede" look was born.
- Scalp Care: Use a clarifying wash once a month to get rid of the mineral buildup that makes dark hair look dull.
Sydney Sweeney has proven that you don't need to be a "blonde bombshell" to be the most interesting person in the room. By embracing her natural brunette roots, she's actually opened up more doors for grittier, more serious roles. It’s a lesson in not letting a specific "look" define your entire career. Whether she goes back to blonde for Euphoria Season 3 or stays in her dark era, the brunette transition has officially solidified her as a style chameleon.
