This one shampoo does it all and is suited to all hair types including colour-treated hair, thinning hair and is suitable for use on hair extensions. Most shampoos are loaded with unnecessary additives like silicones, conditioning agents and pearlising agents that have nothing to do with cleansing and do not easily rinse off. Because shampoo is the only product that is massaged into the scalp, it should never contain ingredients that are engineered to stay behind. COLOR WOW Color Security Shampoo delivers the ultimate dream clean because it is uniquely formulated without any typical film-forming ingredients that stick to the hair and scalp.Sulfate-free formula is gentle as water on the cuticle. Keeps colour looking first-day fresh because it rinses clean and removes build up. Unique anti-thinning formula leaves nothing behind to block follicles and impede new hair growth. Ideal for extensions because it is silicone-free and does not contain conditioners.
