Abstract
Abstract Disclosed herein are cationic hair conditioning compositions comprising an amine oxide; and, water and sufficient acid to provide a pH for said composition of about or below the isoelectric pH of hair protein and an amine oxide concentration from about 0.1% about 10% based on the total weight of said hair conditioning composition. Also disclosed are neutralizer conditioning compositions comprising in addition to the components of the cationic hair conditioning compositions, an oxidizing agent.
