What is the main purpose of using shampoo during hair washing?

The primary purpose of using shampoo during hair washing is to cleanse both the hair and the scalp. Shampoo is formulated with specific surfactants that create a lather when mixed with water, which helps to lift and remove dirt, oil, product buildup, and other impurities from the hair and scalp. This cleansing action is essential for maintaining scalp health and ensuring that hair looks and feels clean.

While adding fragrance, providing conditioning benefits, and enhancing hair color can be attractive features of some hair care products, they are not the primary functions of shampoo. Fragrance may be present in shampoo, but it serves more as an additional sensory quality than a core functional aspect. Conditioning benefits are typically associated with conditioners rather than shampoos, although some shampoos may have mild conditioning properties. Enhancing hair color is generally the purpose of hair color treatment products rather than shampoo. Therefore, the main focus of shampoo is its ability to effectively cleanse the hair and scalp.
