ABSTRACT
Hair soil, from whatever sources, has major ramifications on how the hair looks. Soiled hair is dull, greasy, and stringy, and becomes difficult to manage and style. This chapter focuses on areas of hair cleaning. It explores hair sebum: its composition and its effects on hair aesthetics. The chapter presents a brief description of the mechanism of shampoo actions. It discusses the various aspects of shampoo performance and shampoo properties. The chapter reviews the different types of shampoos and the essential ingredients for shampoo formulations. Hair oiliness is a consequence of having too much sebum depositing on the hair shaft. Baby shampoos are typically formulated mainly with amphoteric surfactants that have a characteristically low level of irritancy. Fatty acid alkanolamides are nonionic surfactants, prepared by reacting a fatty acid or a fatty ester with a primary or secondary alkanolamine.
