Shampoo

Shampoo is a hair care product used primarily to clean hair. Shampoo contains detergent which are a class of surfactants(Surface-Active Agents), such as sodium lauryl sulfate, to remove the oils, dirt, skin particles and grime that build-up in hair over time. Ancient peoples are believed to have employed wood ashes and water for washing and to have relieved the resulting irritation with grease or oil. In the 1st cent. A.D., Pliny described a soap of tallow and wood ashes used by Germanic tribes to brighten their hair.
