Color Wow Dream Filter - 50ml Dream Filter Pre-Shampoo Mineral Remover by Color Wow collects and lifts off minerals from your strands to unveil and protect optimal color. This breakthrough pre-shampoo spray filters out minerals typically found in city and well water that destroy the clarity, intensity and beauty of your hair color. Traces of copper, iron, magnesium, calcium, chlorine and other elements that can otherwise remain in your hair will warp your color over time, making it look yellow, brassy, ashy green, or dull, dark and dingy, depending on the mineral content. This hair treatment is fragrance-free, gluten-free and phthalate-free and works well with all hair types. Key Ingredients: Molecular Chelating Agents: bond with and remove divalent positively charged metals from hair. Polymeric Chelating Agents: bond with and remove heavy metals from hair. Key Benefits: Keep your color looking fresh and bright Highlights are heightened, dimensions are deepened Gentle, non-stripping spray Especially effective on pale shades of blonde, grey, ash and white, which appear lighter and fresher Use Apply Dream Filter to dry hair before shampooing. Spray evenly to saturate hair. Wait for 1-3 minutes, then shampoo. For best results, use Color Wow Color Security Shampoo and Conditioner. Tip: Suggested use is every 3-4 shampoos to keep your color looking fresh and bright. But in cases of frequent exposure to well water or chlorine, you can use it more often (even daily) because Dream Filter is extremely gentle.
