The main purpose of a shampoo is to cleanse the hair and scalp of dirt, oil, and other impurities. Shampoo is formulated with surfactants that help to lift away grime and excess sebum from both the hair and scalp, ensuring cleanliness and a fresh feeling. This cleansing action is crucial for maintaining healthy hair and scalp conditions, as built-up dirt and oils can lead to issues such as dandruff or scalp irritation.

While adding fragrance, styling, and coloring can be aspects of hair care, they are secondary functions that do not define the primary role of shampoo. Fragrance is often an added benefit to make the hair smell pleasant, styling involves products that help shape and hold the hair in place, and coloring is a completely separate process that typically requires different products designed for that purpose. Therefore, cleansing stands out as the central function of shampoo in hair care routines.
