The primary function of shampoo is to cleanse the hair and scalp of dirt, oil, and product buildup. When shampooing, the formulation is designed to interact with the natural oils and impurities present on the scalp and hair. It contains surfactants that effectively lift and remove these elements, ensuring that both the hair and scalp remain clean and healthy. This cleaning process is essential as it prepares the hair for further treatments, such as conditioning or styling, and helps maintain the overall health of the scalp and hair.

While styling products help manipulate the hair into desired shapes or forms, and conditioners are used to add moisture and smoothness, those are not the main purposes of shampoo. Enhancing hair color is also a specific function of certain hair products, like hair dyes or color shampoos, but it does not reflect the main goal of traditional shampooing. Thus, the focus of a shampoo is fundamentally on cleansing, making it vital for good hair care practices.
