Born from Kose's 70+ years of Japanese skincare science, this conditioner refill was created to solve a modern problem: hair damaged by daily stress, pollution, and styling. The Stephen Knoll lab in Tokyo developed this formula after analyzing over 10,000 hair samples, selecting ingredients like patented Ceramide Repair Complex and Amino Silk Protein for their precise repair action. Every batch is produced in a Japanese government-certified GMP facility, ensuring pharmaceutical-grade purity and consistency. It's not just a conditioner; it's a targeted repair system that has become a top-ranked refill choice in Japan for its reliable performance and value, trusted by users who prioritize long-term hair health over quick fixes.

The Kose Stephen Knoll Repair & Control Conditioner Refill - Frizz Control contains a blend of ingredients designed to repair, moisturize, and control frizz for smooth, manageable hair. Key ingredients include water and cetearyl alcohol, which serve as the base and emulsifier to create a creamy texture that spreads easily. Behentrimonium chloride acts as a cationic surfactant, providing detangling and anti-static properties by coating hair strands to reduce friction and frizz. Hydrolyzed keratin and silk amino acids are included to repair and strengthen damaged hair by penetrating the cuticle to restore protein loss and improve elasticity. Panthenol (provitamin B5) functions as a humectant to attract and retain moisture, enhancing hair hydration and softness. Dimethicone, a silicone derivative, forms a protective film on the hair surface to seal in moisture, add shine, and smooth the cuticle for frizz control. Botanical extracts such as chamomile and aloe vera offer soothing and antioxidant benefits, while fragrance provides a pleasant scent. This formulation aims to deliver long-lasting frizz reduction, improved hair health, and enhanced manageability without weighing hair down.
