If you're experiencing dull and matted hair, it's possible you're missing a strong surfactant from your routine. These are essential for removing product build- up and cationic conditioning agents such as the following: Stearalkonium chloride Cetrimonium chloride Cetrimonium bromide Behentrimonium methosulfate Behentrimonium chloride Benzalkonium chloride Cinnamidopropyltrimonium chloride Cocotrimonium chloride Dicetyldimonium chloride Dicocodimonium chloride Hydrogenated Palm Trimethylammonium chloride Lauryltrimonium chloride Quaternium-15 Quaternium-22 Stearamidopropyl dimethylamine (lactate, citrate, propionate) Isostearamidopropyl dimethylamine Isostearamidopropyl morpholine Wheatgermamidopropyl dimethylamine Behenamidopropyl dimethylamine Polyquaternium-xx To effectively remove these ingredients, be sure to use a sulfate shampoo, for example: - Sodium lauryl sulfate - Ammonium lauryl sulfate - Sodium coco-sulfate C14-16 olefin sulfonate is a sulfate free ingredient that can also be used to reset the scalp, since it is also quite a strong detergent.
