Hailey Bieber’s 2021 Met Gala appearance defined the "effortless glamour" era, featuring a custom black velvet Saint Laurent gown and her signature "lived-in" waves. This look prioritized timeless American elegance over avant-garde costumes, solidifying her status as a minimalist style icon. The hair, styled by Jen Atkin, catalyzed a shift toward relaxed, healthy-looking textures that remain influential in 2026.
The Architectural Elegance of the Saint Laurent Gown
When Hailey Bieber stepped onto the Metropolitan Museum of Art’s red carpet for the "In America: A Lexicon of Fashion" theme, she bypassed the literal interpretations of Americana. Instead of stars, stripes, or historical costumes, she and designer Anthony Vaccarello opted for a floor-length, column-silhouette gown in deep black velvet.
The gown’s primary focal point was its plunging neckline, which was framed by a structured, scalloped edge embellished with intricate crystal beadwork. This detail provided the necessary "red carpet spark" without overwhelming the simplicity of the velvet. Velvet is a notoriously difficult fabric for high-intensity lighting; it can absorb too much light and appear flat in photography. However, the high-grade silk-mix velvet used by Saint Laurent retained a subtle sheen that highlighted Bieber’s silhouette.
The choice of Saint Laurent, a French fashion house, for an American-themed gala was a deliberate nod to the "Mid-Century Hollywood" aesthetic. It referenced the era when European couture heavily influenced American socialites and film stars. By 2026, this specific appearance is often cited by fashion historians as the moment Bieber transitioned from a trend-follower to a trend-setter, favoring "Quiet Luxury" long before the term dominated social media.
Analyzing the Hair: The Rise of the "Lived-In" Wave
While the dress provided the structure, the hair provided the vibe. Hailey Bieber’s hair for the 2021 Met Gala was orchestrated by celebrity hairstylist Jen Atkin. The goal was to create a look that felt "undone yet polished," a difficult balance to strike for a formal event.
Technical Breakdown of the Style
The 2021 Met Gala hair trend seen on Bieber was characterized by three specific technical elements:
- The Middle Part: A sharp, precisely centered part served as the anchor for the look. This choice emphasized facial symmetry and provided a clean frame for her Tiffany & Co. jewelry.
- Internal Texture: Unlike traditional red carpet curls that are uniform, these waves featured "internal texture." This means the hair was curled in alternating directions to prevent the sections from clumping together into a single wave.
- Straight Ends: To maintain a modern edge, the last inch of the hair was left uncurled. This prevents the "pageant" look and contributes to the effortless, "off-duty model" aesthetic.
Products and Tools Used
Atkin utilized a combination of high-heat tools and lightweight finishing products. To achieve the look, she reportedly used the Dyson Corrale straightener to create "S-waves" rather than using a traditional curling iron. This technique involves feeding the hair through the plates in a rhythmic "over-and-under" motion.
In terms of products, the focus was on volume at the roots and grit at the mid-lengths. A volumizing mousse was applied to damp hair, followed by a heat protectant. Once dry and styled, a dry texture spray—specifically from Atkin's own brand, OUAI—was used to break up the waves and provide a matte finish that looks better under the harsh flash of paparazzi cameras than a high-shine gloss.
Broader Hair Trends from the 2021 Met Gala
Hailey Bieber was not the only one pushing hair boundaries that year. The 2021 event was a turning point for hair trends, moving away from the heavy extensions and stiff updos of the late 2010s.
| Trend Name | Key Features | Celebrity Example | Technical Difficulty |
|---|---|---|---|
| The Refined Undone Wave | Middle part, straight ends, matte texture. | Hailey Bieber | Moderate |
| High-Octane Ponytails | Extremely long, snatched at the crown, high shine. | Kim Kardashian | High |
| Retro Hollywood Waves | Side part, uniform "S" shape, high gloss. | Megan Fox | High |
| Natural Texture Celebration | Working with original curl patterns, sculptural volume. | Lupita Nyong'o | Expert |
| The 90s Face Frame | Tendrils left out of an updo, sleek finish. | Kendall Jenner | Low |
The Shift Toward Minimalism
The 2021 Met Gala signaled a return to "Healthy Hair." We saw a departure from the "Instagram Face" era of 2016-2019. Celebrities like Bieber and Kendall Jenner opted for hair that looked like it could be achieved at home, even if it required professional intervention. This trend prioritized hair health, using fewer heavy silicones and more lightweight, breathable formulas.
How to Recreate Hailey Bieber’s 2021 Look
Recreating this look requires a focus on preparation rather than just the final curl. Even in 2026, this style remains a go-to for bridesmaids and gala attendees because of its versatility.
Step 1: Foundation and Prep
Start with a lightweight shampoo and conditioner. Avoid heavy masks that might weigh the hair down. Apply a volumizing spray to the roots and a heat-activated primer to the lengths. Blow-dry the hair upside down until it is 80% dry to encourage lift at the scalp.
Step 2: The Parting
Use a rat-tail comb to create a perfect center part. This part must be straight from the forehead to the crown to ensure the hair falls evenly on both sides.
Step 3: Creating the Waves
Using a flat iron or a 1.25-inch curling wand, take 2-inch sections of hair. If using a wand, wrap the hair around it once, leaving the ends out. If using a flat iron, use the "twist and pull" method. Crucial Tip: Alternate the direction of the curls (one toward the face, one away) to create the organic, messy texture Bieber is known for.
Step 4: Breaking it Up
Once the hair has cooled completely, use your fingers (not a brush) to shake out the curls. Flipping your head forward and giving it a gentle shake helps distribute the natural oils and the texture spray.
Step 5: The Finishing Touches
Apply a small amount of finishing cream or hair oil only to the very ends to prevent frizz. Mist a flexible-hold hairspray from about 12 inches away to ensure the style lasts through the night without looking "crunchy."
The Enduring Legacy of the 2021 Appearance
Looking back from the perspective of 2026, the 2021 Met Gala was the definitive start of the "Clean Girl" aesthetic. Hailey Bieber’s look—comprising neutral makeup, a classic black dress, and effortless hair—became the blueprint for the next half-decade of fashion.
It proved that at an event designed for spectacle, simplicity could be the loudest statement. The look also highlighted the importance of the "Power Couple" dynamic on the red carpet, as she was joined by Justin Bieber, who wore a customized suit from his own label, Drew House, in collaboration with Balenciaga. Their coordinated yet distinct styles emphasized a new era of American celebrity fashion that felt more personal and less curated by traditional PR machines.
Essential Accessories: Jewelry and Makeup
To fully understand why the hair worked so well, one must look at the accompanying beauty choices. Hailey’s makeup, done by Mary Phillips, utilized the "underpainting" technique. This involves applying contour and highlighter before foundation, resulting in a glow that appears to come from within the skin.
Her jewelry was equally intentional. She wore a stunning Tiffany & Co. diamond necklace that sat perfectly within the "V" of the YSL neckline. Because her hair was worn down and slightly forward, the necklace provided a necessary point of light, drawing the eye upward toward her face. This synergy between the hair (framing the face), the jewelry (providing light), and the dress (providing structure) is why the look remains a "Best Dressed" staple years later.

Did Hailey Bieber wear a wig or extensions at the 2021 Met Gala?
While many celebrities use extensions for volume at the Met Gala, Hailey Bieber’s 2021 look was praised for its relative naturalism. If extensions were used, they were likely "filler" pieces used to add thickness rather than extreme length, maintaining her natural shoulder-length aesthetic.
Practical Recommendation for Recreating the Look
If you are attempting to recreate this look for a formal event in 2026, the most important factor is hair health. Effortless waves only look "chic" if the hair itself appears hydrated and strong. In the weeks leading up to your event, prioritize bond-building treatments (like Olaplex or K18) to ensure your ends are crisp and your shine is natural. When styling, remember that "less is more"—the goal is to look like you styled your hair in fifteen minutes, even if it took an hour.
