Redken Extreme Length Strengthening Shampoo 300ml is a targeted solution for those looking to achieve longer, stronger hair. Designed for all hair types, this shampoo is enriched with biotin—a key ingredient known to support healthy hair growth by strengthening each strand from root to tip.

As part of Redken’s complete Extreme Length system, this shampoo helps to reduce breakage and fortify damaged hair, making it more resilient over time. With consistent use, hair becomes up to 5x stronger, creating the perfect foundation for maximum hair length and long-term health.
