Kose Stephen Knoll was born from a simple frustration: why do so many hair care products promise color protection but leave hair feeling dry and dull? In Japan, where meticulous care is a way of life, this gap was unacceptable. Our chemists in Tokyo spent over 3 years developing a formula that doesn't just protect color but actively enhances its vibrancy. We selected a patented Amino Acid Complex, proven in 8 clinical trials, and combined it with Japanese silk extract, a traditional ingredient for smoothness. Every batch is produced in a GMP-certified facility in Osaka, adhering to Japan's strict Pharmaceutical Affairs Law. This commitment to precision has made it the top-ranked color-care shampoo in its category for 2 consecutive years, trusted by salons and discerning users who refuse to compromise.

Kose Stephen Knoll Color & Control Shampoo W - Radiant Color & Smoothness is formulated with a blend of specialized ingredients designed to enhance and protect color-treated hair while delivering smoothness and manageability. Key components include sodium laureth sulfate and cocamidopropyl betaine as primary surfactants, which gently cleanse the hair and scalp without stripping color or natural oils. The shampoo incorporates hydrolyzed silk protein and panthenol (provitamin B5) to strengthen hair fibers, improve elasticity, and provide deep conditioning, reducing breakage and frizz. To preserve color vibrancy, it contains UV filters such as ethylhexyl methoxycinnamate, which shield hair from sun-induced fading. Additionally, silicone derivatives like dimethicone and amodimethicone are included to coat the hair shaft, imparting a smooth, glossy finish and enhancing combability. Botanical extracts, such as chamomile and rosemary, offer antioxidant benefits and soothe the scalp, while fragrance compounds ensure a pleasant sensory experience. This combination of cleansing agents, conditioning polymers, color-protective agents, and nourishing extracts works synergistically to maintain radiant color, improve hair texture, and provide long-lasting smoothness for color-treated hair.
