What is the purpose of a shampoo during a barber service?

The primary purpose of a shampoo during a barber service is to cleanse the hair and scalp. Shampoo is specifically formulated to remove dirt, oil, sweat, and product buildup from both the hair and the scalp, promoting overall cleanliness and hygiene. This process is essential before any further hair treatments or styling procedures, as it ensures that the hair is in its best condition for cutting or styling.

While shampooing can leave the hair smelling pleasant, adding fragrance is not the main function. Styling hair often comes later in the service and typically involves products designed specifically for that purpose. Additionally, while some shampoos may provide heat protection, this is generally a secondary benefit rather than the central aim of a shampoo. Thus, the answer focuses on the fundamental role that shampoo plays in maintaining clean hair and a healthy scalp, making the cleansing aspect the correct choice.
