Redken Extreme Shampoo is formulated to strengthen and protect damaged hair while preventing future breakage. Infused with Redken’s Strength Complex, this protein-rich shampoo gently cleanses the scalp and hair while fortifying weakened areas, restoring shine, and improving overall resilience. When used as part of the full Extreme system—including Conditioner and Anti-Snap—clients can experience up to a 75% reduction in breakage. Ideal for hair that needs extra care, it leaves strands stronger, smoother, and more manageable.
