Discover Hailey Bieber's iconic flippy lob routine and Mane 'It's Giving Body' thermal round brush for voluminous, effortless hair in 2026.

Okay, so I was just scrolling through TikTok the other day, and I came across this absolute gem from Hailey Bieber. It was posted back in December 2025, and let me tell you, her hair has been living rent-free in my mind ever since. That perfect, bouncy, flippy lob? Iconic. It's the kind of haircut that makes you want to immediately book a salon appointment and also master the art of the thermal round brush. And guess what? I did my beauty sleuthing thing (a talent I'm weirdly proud of, right up there with identifying every Rhode blush shade in two seconds flat), and I found exactly how she gets that look. The key? It's all about one specific tool and some very intentional styling moves.

So, let's break it down. The real MVP of Hailey's viral "flippy hair and a lip" TikTok is this gorgeous, glowing blue brush. I'm talking about the Mane 'It's Giving Body' Large Hot Thermal Round Brush. The cute blue power button is basically its signature. It just screams "easy beauty for the cuties," which is totally Hailey's vibe. If you're trying to get those voluminous, flipped-out ends, this is the brush you need in your arsenal for 2026.

Hailey's Step-by-Step Flippy Lob Routine

Here’s how she does it, straight from the source:

  1. Start with Damp Hair: She begins with freshly washed hair. No surprise here—clean hair is the best canvas.

  2. Rough Dry: This is key! She uses her Dyson Airwrap without any attachments to get her hair about 80-90% dry. She mentioned in the video that she loves this method and has a Dyson Supersonic on her 2026 wishlist too. Girl, same.

  3. Section & Roll: Now for the main event. She sections her hair and takes the Mane thermal brush through piece by piece. The magic is in the direction:

    • For the Flip: She rolls most of the sections toward her face. When the hair falls, the ends naturally flip outward, creating that bouncy, retro-feeling flip.

    • For Variation: Every so often, she'll roll a section away from her face. This makes the ends curve inward slightly. Mixing these two directions is what gives the style that cool, effortless, "I woke up like this" texture instead of looking too uniform.

  4. Product Play: After heat styling, she adds some products for hold and texture. It's a little hard to see, but based on the bottles, it looks like she's spritzing in Not Your Mother's Clean Freak Dry Shampoo (for volume at the roots) and Mane's Cotton Candy Dry Texture Spray (for that piece-y, lived-in finish).

  5. The Final Flip: She flips her whole head upside down, gives it a shake for maximum volume, and then runs a brush through it—a chic brush engraved with "Hailey," no less.

  6. The "Lip" Part: Obviously, she finishes the look with her Rhode Lip Peptide Liner in what looks like the shade 'Lift' and a mysterious new clear lip product she's been teasing. The full glam is essential!

The Cut Itself: Justine Marjan's Masterpiece

Of course, a great style starts with a great cut. We first saw this lob last weekend, and it feels like it's always been the haircut to have. The genius behind it is celebrity hairstylist Justine Marjan. She spilled all the details in the comments of a Byrdie Instagram post, and I've got the notes for you:

"If you want to recreate, we did a collarbone-grazing blunt cut with slight face-framing layers and point cut around the front."

Let's translate that into salon-speak for your next appointment:

Feature What It Means Why It Works
Collarbone-Grazing Length Hits right at the collarbone. The perfect lob length—not too short, not too long. It's super versatile and flattering.
Blunt Cut The ends are cut straight across in one clean line. Creates the illusion of incredible thickness and health. It's the foundation for that "flip."
Slight Face-Framing Layers Very subtle layers cut around the front of the face. Softens the look without removing too much weight. It makes the style more dynamic and modern.
Point Cutting The stylist uses the tips of the scissors to cut into the ends vertically. This technique texturizes the ends, preventing them from looking too heavy or helmet-like. It helps the hair move and flip more easily!

Why This Look is EVERYTHING for 2026

Let's be real, this isn't just a passing trend. The flippy lob is having a major moment because it hits all the right notes for the current beauty mood:

  • It's Retro & Modern: It gives off major 70s vibes but feels completely fresh and now. It's nostalgic without being costumey.

  • Low-Maintenance High-Impact: The cut itself is fairly simple (a blunt lob), but the styling technique (those strategic flips) makes it look expensive and editorial.

  • Universally Flattering: According to stylists, a lob that grazes the collarbone is one of the most universally flattering lengths. The slight face-framing layers can be customized for any face shape.

  • Works with 2026 Trends: It perfectly complements other big trends like "Cherub Cut" layers and "Birkin Bangs"—you can easily incorporate those elements into this base cut.

So, if you're looking for a hair refresh this year, this is your sign. Book that appointment, show your stylist Justine Marjan's notes, and invest in a good thermal round brush (looking at you, Mane brush). Start with the cut, master the flip, and you'll be serving effortless, bouncy glam in no time. Trust me, your kindergarten-art-contest-winning self will thank you.
