What is the main function of shampoo in hair care?

The main function of shampoo in hair care is to cleanse the hair and scalp. Shampoo is specifically formulated to remove dirt, oil, and product buildup from the hair and scalp, helping to maintain cleanliness and a healthy environment for hair growth. It achieves this by using surfactants, which bind to the oils and impurities, allowing them to be rinsed away with water.

While other functions like moisturizing, conditioning, and styling are important in the overall hair care routine, they are not the primary purpose of shampoo. Moisturizers and conditioners are typically applied after cleansing to address hydration and manageability, while styling products are used to achieve specific looks or hold styles. Therefore, the correct choice highlights the essential role of shampoo as a cleansing agent in hair care.
