Get Your Shine Back, Naturally

Repairs surface damage to restore your hair's natural light-reflecting ability, giving you a healthy glow that doesn't look artificial or oily.

Cuts Down Detangling Time & Stress

Makes wet hair noticeably smoother and more manageable, so combs glide through with less pulling and fewer tears. Customers say it 'makes combing easy' even after bleaching.

Protects Your Styling Investment

Helps maintain the integrity of colored or permed hair by reinforcing its structure, so your style lasts longer and looks fresher. Users report color 'stays vibrant' and curls 'hold their shape'.

Born from a partnership between Japan's Kose and New York stylist Stephen Knoll, this hair pack was created for a modern problem: hair damaged by styling, pollution, and stress. The formula focuses on intensive repair, using a targeted blend of ceramides and amino acids to rebuild from within. Every batch is made in a certified Japanese GMP facility, ensuring pharmaceutical-grade purity and consistency. It's not just a treatment; it's a restoration protocol developed by experts who understand that healthy hair is a cornerstone of confidence. This commitment to quality has made it a top-ranked choice for damage repair in its category, trusted by users who see their hair as an investment.

The Kose Stephen Knoll Repair & Control Hair Pack W - Intensive Damage Repair by Stephen Knoll New York (Kose) features a carefully curated blend of ingredients designed to restore and protect damaged hair. Key components include hydrolyzed keratin, which penetrates the hair shaft to rebuild protein structure and enhance strength, reducing breakage and split ends. Ceramides are incorporated to reinforce the hair's lipid barrier, sealing in moisture and improving elasticity for smoother, more manageable strands. Panthenol (provitamin B5) acts as a humectant, attracting and retaining hydration to combat dryness and add shine. Silicones such as dimethicone provide a lightweight coating that smooths the cuticle, reducing frizz and enhancing gloss without weighing hair down. Natural oils like argan oil deliver antioxidants and fatty acids to nourish the scalp and hair, promoting softness and resilience. Additionally, amino acids support repair at a molecular level, while UV filters help shield hair from environmental stressors. Together, these ingredients work synergistically to deeply condition, repair damage from heat styling or chemical treatments, and restore hair's health, leaving it stronger, shinier, and more resilient with regular use.
