Redken Color Extend Shampoo, 33.8 Oz
Redken Color Extend Shampoo in the 33.8-ounce (oz) size is a gentle and sulfate-free shampoo specially formulated to protect and maintain the vibrancy of color-treated hair. The larger size is ideal for those who frequently use the product or have long or thick hair.

The Color Extend Shampoo is part of Redken’s Color Extend line, which focuses on preserving and enhancing hair color. It is designed to extend the life of hair color by preventing fading and maintaining color intensity.

The sulfate-free formula of the Color Extend Shampoo is gentle on the hair and helps to prevent color stripping. Sulfates are commonly found in many shampoos and can strip away the natural oils and color molecules from the hair, leading to color fading. By omitting sulfates, this shampoo helps to maintain the integrity and vibrancy of your hair color.
