Simone Biles, the iconic eight-time Olympic gold medalist, is known for her strength both on and off the mat. Her commitment to fortitude extends to her hair care routine, where she relies on the K18 Leave-In Molecular Hair Mask to maintain strong, resilient strands that can withstand the rigors of her athletic lifestyle. The best part? This high-performance hair treatment is available for under $30 on Amazon.
Biles praises the K18 treatment as a “game changer,” highlighting how it gives her “the confidence to switch it up and take risks—without sacrificing the health of [her] hair.” According to K18, the mask is clinically proven to reverse damage and restore hair strength, smoothness, and softness. Its effectiveness is attributed to a patented peptide that mimics the structure of hair follicles, leading to renewed strands.
How to Use the K18 Leave-In Molecular Hair Mask
To achieve the best results, apply up to three pumps of the hair mask to towel-dried hair after shampooing. Skip the conditioner to allow the treatment to fully penetrate the strands. Let the product sit for four minutes before styling as usual—no rinsing required.
The K18 Leave-In Molecular Hair Mask has garnered over 12,900 perfect ratings on Amazon and was purchased by more than 20,000 people in the past month alone. One enthusiastic reviewer described it as a “hair growth miracle,” noting its ability to reverse breakage and significantly strengthen hair.
Simone Biles’ endorsement of the K18 Leave-In Molecular Hair Mask underscores its effectiveness and affordability, making it a must-try for anyone seeking stronger, healthier hair.
