HYDROLYZED CELLULOSE

Safety grade: A

This is a broken-down form of cellulose, a natural fiber found in plant cell walls, that has been treated to make it smaller and easier for cosmetics to use. It works like a lightweight powder that absorbs moisture and helps style or condition hair.

This ingredient absorbs moisture and sweat to reduce odor, conditions and smooths the hair shaft, and helps hair hold styles when used in waving or straightening treatments.
