Caro-co, "America’s Shampoo from the Carolinas," was produced in Union, South Carolina, in the 1920s. Advertisements for "The Sunny South’s creation for all women who want beautiful hair" claimed Caro-co would keep hair and scalp clean and healthy if used regularly. The quick rinsing formula was "scientifically" prepared from the "pure" oil of cocoanut [coconut] to "drive away" dandruff. The shampoo had "no excess" alcohol and was advertised as good for both men and women.
Coconut oil is a popular ingredient in many shampoos. Sodium lauryl sulfate, a foaming agent widely used in shampoos, soaps, and other personal care products, is derived from coconut oil.
