Kourtney Kardashian Hair: What Most People Get Wrong

Honestly, if you look at the Kardashian-Jenner clan, the hair evolution is usually a high-speed chase of neon wigs, waist-length extensions, and platinum bleach jobs that probably take fourteen hours in a salon chair. But Kourtney is different. Her vibe has always been a bit more "I woke up like this," even if we all know there’s a team involved. Lately, Kourtney Kardashian hair has become the blueprint for women who want to look expensive without looking like they're trying too hard. It’s that effortless, rock-wife, "I just chopped my bangs because I have a fever" energy that actually feels relatable.

People think she just sticks to a sleek black bob. They’re wrong.

The Viral "Witchy" Transformation

In late 2025, Kourtney went through what she called her "Witchy Season." It started with a trip to Salem and ended with her literally cutting her own bangs while sick with COVID-19. You’ve probably been there—that 2:00 AM urge to reinvent your entire identity with a pair of kitchen scissors. Except, when Kourtney does it, it becomes a global trend.

She eventually polished the look with the help of her go-to stylist, Dimitris Giannetos. He dubbed it the "YSL Haircut." It’s basically a high-fashion, 1970s-inspired feathery dream. Think Farrah Fawcett but with a darker, edgier twist. Giannetos used Great Lengths tape-in extensions to add enough volume to make the layers pop. It’s a far cry from the flat-ironed "glass hair" we saw her rocking during the early Poosh days. This look is about movement. It’s about being "fluffy" and "bold."

Why the Bob Still Matters

Before the YSL shag, there was the bob. The Kourtney Kardashian bob is probably the most requested haircut of the last three years. Why? Because it’s a power move.

When she first chopped her long hair into that blunt, chin-length cut for Vogue Arabia, it signaled a shift. She was leaving the "toxic environment" of the old show and leaning into her own brand. The bob is low-maintenance, but it requires a very specific technique. It’s not just a straight cut; it’s often slightly shorter in the back to give it that "A-line" swing, usually styled with a crisp middle part or a deep side flip for more volume.

The Secret Sauce: It’s Not Just Products

You can buy all the texture sprays in the world, but Kourtney’s hair health actually starts in her kitchen. Her longtime stylist Andrew Fitzsimons has been vocal about this for years. He’s gone on record saying that her "glass shine" comes from a high-protein diet—lots of fish, eggs, and nuts.

• The Avocado Mask: Kourtney famously uses an at-home mask inspired by her morning smoothie. It’s basically avocado, lemon, olive oil, and honey. Does it work? It’s messy as hell, but the fatty acids in the avocado are legit for smoothing down the cuticle.
• The Apple Cider Vinegar Rinse: She uses this to get rid of product buildup without stripping natural oils.
• Cold Setting: One of Fitzsimons' best tips is the "cold blast." When you’re done blow-drying, hit the cold button. It seals the hair cuticle instantly and reflects light. That’s how she gets that mirror-like finish without using three pounds of silicone oil.

Let’s Talk About the Gray Hair

One of the coolest things about Kourtney—and something she doesn't get enough credit for—is how she treats aging. While her sisters might be sprinting to the colorist at the first sign of a silver strand, Kourtney once told Kylie she "lives for them" when offered a pair of tweezers. She’s been spotted with visible silver roots between salon visits, and she just doesn't seem to care. It fits her "Lemme" wellness ethos: being natural, being real, and not panicking about the passage of time.

Is Lemme Grow Actually Worth It?

If you've spent any time on Instagram, you've seen the Lemme Grow capsules. Most "hair gummies" are just sugar and biotin. Kourtney’s version is a bit different because it uses Cynatine HNS, which is a solubilized form of keratin.

Most hair is made of keratin, but you can't just eat a steak and expect it to go straight to your split ends. The solubilized version is supposed to be more "bioavailable," meaning your body can actually use it. Does it work? If you’re deficient in zinc or B6, you’ll see a massive difference. If your diet is already perfect, it’s mostly just a nice insurance policy for your hair follicles.

How to Get the Look (The Real Way)

If you’re heading to the salon to copy Kourtney’s current vibe, don't just ask for "layers." You need to be specific.

1. Ask for the "Internal Weight" removal. Kourtney’s hair is thick. To get that feathery YSL look, your stylist needs to use a razor or thinning shears on the mid-lengths so the hair moves instead of just sitting there like a helmet.
2. The Curtain Bangs: They shouldn't be too short. They should hit right at the cheekbone to frame the face.
3. The Color: It’s almost never true black. It’s usually a "Darkest Brown" or "Natural Black." True black can look flat and "inky" on camera. A dark brown reflects more light and looks more expensive.

Kourtney has mastered the art of the "rebrand haircut." Whether it’s the "Witchy" bangs or the blunt bob, she uses her hair to tell people exactly who she is at that moment. Right now, she’s in her "YSL 70s rock" era, and honestly? It’s the best she’s ever looked.

To maintain this at home, stop over-washing. Kourtney and her team swear by rinsing with water only between "real" washes and using a silk pillowcase to stop the friction that causes frizz. It's simple, but it's the difference between a frizzy mess and celebrity-level shine.

Your Next Steps for Healthy Hair:

• Incorporate a Weekly Scalp Exfoliation: Use a physical scrub or a chemical exfoliant (like salicylic acid) once a week to remove buildup that stunts growth.
• Switch to a Silk Pillowcase: This is the easiest way to prevent split ends while you sleep.
• Try a Cold Rinse: The next time you wash your hair, end the shower with thirty seconds of the coldest water you can stand to seal the hair cuticle for maximum light reflection.
