Simone Biles Is K18’s New Brand Ambassador

Gymnast Simone Biles has joined biotech haircare brand K18 as a brand ambassador fronting its inner-strength campaign.

The multi-year partnership with Biles underscores the brand’s commitment to prioritizing hair health from a biology-first approach. Its latest campaign featuring Biles will follow her routine on and off the mat and encourage consumers to “feel what’s possible” with K18. The national TV commercial will be unveiled this month.

“Simone Biles is synonymous with pushing boundaries and her impact extends far beyond her sport,” said Suveen Sahib, CEO, K18. “As our newest brand ambassador, Simone will bring her transformative energy to K18. This partnership is a testament to resilience, the power of science in elevating self-expression, and the belief that when we tap into our inner strength, anything is possible —whether it’s a gold medal performance or transforming the future of haircare.”

K18’s proprietary biotechnology patented K18 Peptide is a novel molecule that works deep inside the hair fiber at a molecular level to reverse damage in four minutes, per the brand.

“I feel most natural and beautiful when I let my hair down, especially after competing in a bun or ponytail,” said Biles. “The K18 molecular repair hair oil and leave-in molecular repair hair mask have been game changers for me, so my hair stays healthy amid all the stress I put it through, including with extensions. My hairstylist and I have really felt a difference in my hair after using K18 and she’s great about always having their products available to me, especially when I’m traveling or on production shoots.”

K18 will also partner with Biles’ longtime professional hairstylist, Jasmine Johnson, as a K18 ambassador to share the stylist’s perspective on the benefits of K18 – particularly for those with texture and hair extensions.
