The primary purpose of using a shampoo cap is to cleanse and hydrate hair without the need for water. This is particularly beneficial in scenarios where traditional bathing facilities might not be available, such as in hospitals or for individuals with limited mobility. Shampoo caps are designed with ingredients that help remove dirt and oil from the hair while also conditioning it. They are effective for maintaining cleanliness and moisture in the hair, providing convenience and ease of use for those who may not be able to wash their hair in the conventional way.

Other options relate to different aspects of hair care or styling that do not align with the main function of a shampoo cap. For instance, quickly styling hair, adding volume, or enhancing hair color each focuses on altering the appearance or texture of the hair rather than its cleanliness or hydration.
