Essential Shampoo Base contains only skin and hair-friendly ingredients, with no lauryl sulfate or PEG detergents. The result is a shampoo for all hair types, with gentle but effective cleansing power and conditioning agents. It is concentrated, so a little will go a long way. We chose our ingredients because we wanted to offer an excellent shampoo free of problematic lauryl sulfate and PEG (polyethylene glycol) detergents. All the cleansing agents used are all vegetable oil-derived, free of any toxic residues (such as dioxanes and nitrosamines) and are very gentle on the hair – yet effective and conditioning.
