The primary function of a shampoo during a service is to cleanse the hair and scalp. This involves removing dirt, oil, product buildup, and environmental pollutants that can accumulate over time. A well-formulated shampoo works by breaking down the oils and impurities on the scalp and hair, allowing them to be rinsed away with water.

Cleansing the hair and scalp is essential not only for hygiene but also for preparing the hair for subsequent services, such as conditioning, cutting, or styling. By ensuring that the hair and scalp are clean, the shampoo creates a healthier environment that can enhance the effectiveness of other products used during the service.

While other functions, such as protecting hair color or promoting hair growth, may be relevant to specific products or procedures, the fundamental role of shampoo as a preparatory step in hair care is to provide a thorough cleansing.
