What is the primary purpose of a shampoo?

The primary purpose of shampoo is to cleanse the hair and scalp. This involves removing dirt, oil, product buildup, and impurities, which helps maintain a healthy scalp and clean hair. Regular cleansing is vital because the scalp can accumulate oils and debris, which may lead to various issues such as dandruff, scalp irritation, and hair loss.

Shampoos are formulated with specific ingredients that facilitate this cleansing process, often containing surfactants that help lift and wash away the unwanted materials without stripping the hair of its natural moisture. While other options like adding fragrance, enhancing hair color, or protecting against UV rays may be important aspects of some specialized products, they do not represent the fundamental role of shampoo. The primary focus remains on achieving cleanliness, setting the stage for subsequent hair care practices, such as conditioning and styling.
