Nioxin Age Defense Shampoo is a rejuvenating, anti-aging formula designed to promote fuller, shinier, and healthier-looking hair over time. This gentle yet effective shampoo purifies the scalp and hair by removing buildup and impurities, helping to restore natural shine and improve visible fullness for more youthful-looking results. Powered by a NutriActive+ Complex with niacinamide, along with caffeine and BHA, it supports scalp health while targeting early signs of hair aging such as thinning, dullness, and greying. The sulfate- and silicone-free formula deeply detoxifies to create the ideal foundation for healthy hair, leaving strands feeling clean, balanced, and revitalized. Dermatologically tested and safe for color-treated hair, it delivers a refreshed, lightweight finish with every wash.
