K18 Hair Puts Biotech Front and Center with Simone Biles

Olympic icon Simone Biles is once again the face of K18 Hair’s latest campaign, but this time, the focus isn’t on her medals.

It’s on molecular hair repair.

Shot between Houston and Los Angeles, the new campaign from biotech haircare brand K18 captures Biles mid-training and mid-transformation, leaning into the power of unscripted moments.

The spot, directed by Heinz Kobernik of Dreamboat, aims to reveal the Olympic gymnast’s off-season routines through a lens of intimacy and authenticity.

“I wanted to move away from a traditional commercial approach and lean into something more real and imperfect,” Kobernik said, adding that the goal was to capture Biles’ essence without over-polishing.

Rather than rely on scripted lines or overproduced settings, the production embraced spontaneity.

Cameras kept rolling between takes, collecting footage that reveals the often-unseen grind of Biles’ everyday life, including sweat, setbacks, and all.

The result was a raw, humanizing portrait that also doubles as a showcase for K18’s biotech hair innovation.

“Our goal with this brand relaunch was to create a suite of content that’s responsive to a myriad of platforms and creative needs,” said Peter Williams, executive producer at Dreamboat.

The campaign launched across digital and social platforms in July, expanding K18’s push to connect haircare with self-care, especially for active consumers.

Notably, the brand and the athlete's partnership kick-started last year, with a campaign that showed that you don't need to sacrifice proper hair care when you take risks. 

Raw Footage, Real Impact

The spot's unscripted footage works on multiple levels.

"I usually train six to seven hours a day, so after an intense workout, my hair usually feels wet, humid, and just gross," Biles tells the viewers, as we see a montage of the athlete doing her workout regimen.

The solution to her hair problem? K18. 

She explains how the spray does not feel gritty, and instead makes her feel clean and ready to go "from gym to date night."

For fans, the campaign might come as a new perspective on Biles.

But for the brand, it’s a smart play in celebrity marketing, as it moves away from glossy perfection toward a more grounded form of influence.

Furthermore, the spot also highlights Dreamboat’s systems-based approach to content.

Rather than build a one-off ad, the company created an asset library designed for scale.

It's something brands increasingly demand in an omnichannel environment.

The hero spot anchors a larger rollout that spans Instagram, TikTok, and other digital touchpoints.

Additional content shows Biles interacting with K18 products mid-routine, emphasizing the science behind the product without straying from storytelling.

Our Take: Can Brands Skip the Script?

Something is refreshing about a campaign that isn’t trying so hard to be perfect.

We’ve seen plenty of celebrity endorsements, but K18 and Dreamboat flip the script by letting Simone Biles be her natural self.

That space to be candid, strong, and still is what makes this work.

But more than that, it's a sign of where beauty campaigns are headed.

Polished ads feel dated, and being authentic is now a business imperative.

If brands can match that energy with performance-driven products, the results will follow.
