What is a Sulfate-free Shampoo?
All Kenra® Platinum Shampoos are sulfate-free to ensure maximum color retention. These gentle formulations cleanse with a luxurious lather to deliver the ultimate softness, body and shine to color-treated hair. Shampoos containing sulfates can strip hair color, and most shampoos contain Sodium Laureth Sulfate as a primary ingredient. This harsh cleanser aggressively scrubs your hair, causing damage and threatening color.
