Simone Biles is K18’s Newest Brand Ambassador


Simone Biles is already the most decorated gymnast in history and an outspoken advocate for mental health, but now, she can add one more exciting item to her ever-growing list of achievements: K18 brand ambassador. 

The biomimetic hairscience brand recently announced a multi-year partnership with Biles that will see the Olympic gymnast become the face of the brand’s latest “Inside-Out” campaign through 2026 and their longest ambassador partner. As K18’s brand ambassador, Biles will highlight how the impossible is made possible with her own elevated hair routine that promotes self-expression and the power of inner strength. 

In alignment with K18’s shared commitments surrounding empowerment, their “Inside-Out” campaign featuring Biles will follow her routine both on and off the mat, encouraging consumers to “feel what’s possible” with K18. According to the brand, a national TV commercial is set to debut later this month.

“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 alway having their products available to me, especially when I’m traveling or on production shoots.”

Along with partnering with Biles, K18 will also be tapping Biles’ longtime professional hairstylist, Jazmine Johnson, to be a K18 ambassador, as well. She will share the stylist’s perspective on the benefits of K18—especially for those with textured hair and hair extensions.

“Simone Biles is synonymous with pushing boundaries and her impact extends far beyond her sport,” says Suveen Sahib, Co-founder and CEO of 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.”
