Wrixty Coconut Milk is used for the removal of oils, dirt, skin particles, dandruff, environmental pollutants and other contaminate particles that gradually buildup in hair. At a basic level, the function of the shampoo is removal of the thin layer of oily material known as sebum. Produced by sebaceous glands in the skin, it coats and protects the hair. Unfortunately, sebum also acts as a virtual magnet for dirt and residue from hair treatment products.
