What is the primary role of a shampoo?

The primary role of a shampoo is to cleanse the hair and scalp. Shampoo is formulated with various surfactants that work to remove dirt, oil, and product buildup from the hair and scalp. This cleansing action is essential for maintaining healthy hair and scalp conditions, as it helps to prevent issues such as dandruff, itchiness, or greasy hair.

While conditioning and styling are important aspects of hair care, they are not the primary functions of shampoo. Conditioners are specifically designed to add moisture and smoothness to the hair after it has been cleansed, while styling products are meant to help shape and hold a particular hairdo. Color enhancement falls under hair coloring products, which serve a very different purpose focused on altering the hair's appearance rather than cleansing. Thus, the purpose of shampoo firmly centers around its ability to cleanse, making it vital in a regular hair care routine.
