Which product is primarily used to cleanse the hair and scalp?

Shampoo is specifically formulated for cleansing the hair and scalp. It typically contains surfactants that help remove dirt, oil, and buildup from styling products. The primary function of shampoo is to provide a deep clean while maintaining the health of the hair and scalp. Additionally, many shampoos are designed to address specific hair types or concerns, such as dryness or oiliness, further enhancing their role in hair care.

Conditioners are designed to moisturize and detangle the hair after cleansing, while hair masks provide deep conditioning treatment and nourishment. Scalp treatments focus on specific issues affecting the scalp, such as dandruff or irritation, but do not serve the main purpose of cleansing. Therefore, in the context of hair care, shampoo is the go-to product for effectively cleaning both the hair and the scalp.
