Simone Biles has been unveiled as an ambassador for haircare brand K18, following in the footsteps of personalities including Sofia Richie Grainge and Alix Earle.

A spokesperson for the brand commented 'Simone was a natural fit - not only because she’s the world’s most decorated gymnast - but because she fundamentally showcases how the impossible is possible when you focus on best understanding your biology, and work with your biology'.
