What is the primary purpose of a shampoo in a salon treatment?

The primary purpose of shampoo in a salon treatment is to clean the hair and scalp. Shampoo is specifically formulated to remove dirt, oil, product buildup, and other impurities from the hair and scalp surface. This cleansing process is essential not only for hygiene but also for preparing the hair for additional treatments. Clean hair is more receptive to conditioning, styling, and treatment products, leading to better overall results in hair care and styling.

While styling the hair, adding volume, and maintaining color are important aspects of hair care, they are not the foundational roles of shampoo. Shampoo serves as the first step in the hair treatment process, ensuring that the hair is clean and healthy before any other products are applied. This makes it a crucial element in any salon service, as it sets the stage for effective treatment and care.
