Week 4+: With consistent use, hair develops a stronger, more resilient feel, with a healthy-looking shine and reduced breakage during styling.

Born from a partnership between Japan's Kose Corporation and acclaimed stylist Stephen Knoll, this shampoo was created for those whose hair feels tired from modern life—heat styling, environmental stress, and hard water. The formula centers on a patented amino acid complex, selected for its ability to mimic the hair's natural building blocks without heavy silicones. Every batch is produced in a Japanese factory with GMP certification, ensuring pharmaceutical-grade precision. It underwent 8 separate clinical evaluations on hair strength and manageability before launch. Now, it's consistently ranked as a top choice for damage care in Japan's competitive haircare market, trusted by users who've tried countless alternatives.

Kose Stephen Knoll Repair & Control Shampoo W Refill - Damage Care is formulated with a blend of ingredients designed to repair and strengthen damaged hair. Key components include hydrolyzed keratin, which penetrates the hair shaft to restore protein loss and improve elasticity, reducing breakage. Panthenol (provitamin B5) acts as a humectant to attract and retain moisture, enhancing hair softness and manageability. Silicone derivatives like dimethicone provide a protective coating that smooths the cuticle, reducing frizz and adding shine. Botanical extracts such as rosemary and chamomile offer antioxidant and soothing properties to support scalp health. Additionally, amino acids like arginine help fortify hair structure, while mild surfactants ensure gentle cleansing without stripping natural oils. This combination targets damage repair, moisture retention, and overall hair vitality for a healthier appearance.
