Redken Extreme Length Shampoo is a fortifying formula enriched with biotin, designed to reduce breakage and promote hair growth. It gently cleanses while strengthening the hair fiber, allowing hair to grow up to 6 inches (approximately 15 cm) in one year. This shampoo is ideal for long or fragile hair, even color-treated or bleached hair, as it helps prevent split ends and maintain healthy lengths. Used in conjunction with the conditioner and leave-in treatment from the Extreme Length range, it delivers optimal results.
