Lightweight Enough for Fine Hair

Even if your hair is thin or gets oily, this mist hydrates without making it look flat or greasy. It adds body, not weight.

Stephen Knoll was founded in Tokyo by a team of cosmetic chemists who noticed a gap: hair mists that smelled nice but did little for actual hair health. They developed Hydro Renew Mist to address the modern-day hair stressors of dry air, heat styling, and environmental pollution. The formula centers on a patented 3D Hydration Complex, selected for its ability to bind moisture at multiple structural levels within the hair shaft, not just coat the surface. Every batch is produced in a Japanese GMP-certified facility and undergoes 23 separate quality checks for purity and potency. Since its launch, it has remained a top-ranked hydrating treatment in Japan's professional beauty category for over 24 months, trusted by stylists and consumers alike for delivering real, measurable repair.

Stephen Knoll Hydro Renew Mist Moisture & Repair - 250ml Hydrating Hair Mist by Kose is formulated with a blend of key ingredients designed to hydrate, repair, and protect hair. Water and glycerin serve as the primary hydrating agents, attracting and retaining moisture to combat dryness and improve hair elasticity. Hydrolyzed keratin is included to strengthen and repair damaged hair by replenishing protein, reducing breakage, and smoothing the cuticle for enhanced shine. Panthenol (provitamin B5) penetrates the hair shaft to moisturize and add volume while improving manageability. Sodium hyaluronate, a form of hyaluronic acid, provides deep hydration and helps maintain hair's moisture balance for long-lasting softness. Botanical extracts, such as chamomile or aloe vera, offer soothing and antioxidant properties to protect hair from environmental stressors. Silicone derivatives, like dimethicone, create a lightweight coating that smooths frizz, adds shine, and provides heat protection during styling. This combination of ingredients works synergistically to deliver intense hydration, repair damage, and leave hair looking healthy, manageable, and revitalized.
