What is the purpose of a shampoo?

The primary purpose of shampoo is to cleanse the scalp and hair of impurities and excess oil. Shampoos contain surfactants that help to remove dirt, sweat, product buildup, and oils from the hair and scalp. This cleansing action is vital for maintaining healthy hair and scalp hygiene, as it prevents issues such as dandruff, itching, and an oily appearance.

While adding color, conditioning, and providing heat protection are important aspects of hair care, they are not the main function of shampoo. Other products, such as hair dyes, conditioners, and heat protectants, are specifically formulated for those purposes. Thus, the focus of shampoo use is on its ability to clean effectively, ensuring that the hair remains healthy and manageable.
