1. Wet your hair and scalp thoroughly with warm water. 2. Dispense one pump (about the size of a quarter) into your palm. 3. Gently massage the cleanser into your scalp with your fingertips for 60 seconds. Focus on areas that feel tight or itchy. 4. Rinse completely with lukewarm water. 5. Follow with your regular conditioner on the lengths of your hair, avoiding the scalp. For best results, use daily or every other day. Timeline Expectations: Week 1: You'll notice your scalp feels 'clean but not stripped' and 'refreshed'. The tight, uncomfortable feeling starts to ease. Week 2-3: Cumulative cleansing helps remove buildup. Your scalp feels more balanced, and you may use less styling product as your natural texture improves. Week 4+: With consistent use, your scalp maintains a healthier environment. Long-term users report it's become an 'essential part' of their routine for lasting comfort.

The Kose Stephen Knoll Scalp Care System was born from a simple observation: modern life is tough on your scalp. Stress, hard water, and styling products can leave it feeling tight and uncomfortable. Kose, a trusted Japanese beauty leader since 1946, partnered with expert Stephen Knoll to create a solution. They focused on a gentle, effective cleanser that respects your scalp's natural balance. Every ingredient is selected for purity and purpose, sourced from Japan's strictest suppliers. The formula is manufactured in a certified Japanese GMP facility, ensuring pharmaceutical-grade quality. It's not just a cleanser; it's a reset button for your scalp, developed by experts who understand that a healthy scalp is the foundation of great hair. This refill version is a direct response to loyal customers who call it their 'staple' and 'the only thing that works'.

The Kose Stephen Knoll Scalp Care System Cleanser Refill - 400ml is formulated with a blend of ingredients designed to cleanse and nourish the scalp while maintaining its natural balance. Key components include water as the base solvent, sodium laureth sulfate as a primary surfactant to create a rich lather and effectively remove dirt, oil, and product buildup without excessive stripping. Cocamidopropyl betaine is included as a secondary, milder surfactant to enhance cleansing while being gentle on the scalp, reducing potential irritation. Glycerin serves as a humectant to attract and retain moisture, helping to prevent dryness and maintain scalp hydration. Sodium chloride is used as a viscosity modifier to adjust the product's consistency for optimal application. Citric acid acts as a pH adjuster to ensure the cleanser aligns with the scalp's natural acidic environment, promoting a healthy barrier function. Fragrance is added for a pleasant sensory experience, though it may vary by formulation. Additional ingredients such as preservatives like methylchloroisothiazolinone and methylisothiazolinone are included to maintain product stability and prevent microbial growth. This combination aims to provide a thorough yet gentle cleanse, supporting scalp health by removing impurities while preserving moisture and pH balance, which can contribute to reduced flakiness, itchiness, and overall improved scalp comfort for users.
