Hydrolyzed Casein

Safety grade: A

This ingredient is a broken-down form of casein, a protein naturally found in milk. It's created by splitting the casein protein into smaller pieces that can easily penetrate and coat hair and skin.

It moisturizes and softens both hair and skin by forming a protective layer that helps lock in hydration and improve texture.
