Final answer:
The protective product used during a relaxer service to prevent irritation is called a base cream or protective base, which acts as a barrier between the scalp and the chemicals.
Step-by-step explanation:
The product that is used to protect the scalp from irritation during a relaxer service is typically known as a base cream or protective base. This cream is usually petroleum-based and is applied to the scalp, ears, and any other areas that may come in contact with the relaxer to help prevent chemical burns and other forms of irritation. The base cream creates a barrier between the relaxer and the skin, thus offering protection against the harsh chemicals used in the relaxer service.
The product protecting the scalp from irritation in a relaxer service is known as a scalp protectant or a scalp barrier cream. It is applied to the scalp before applying the relaxer to protect the skin from the harsh chemicals in the relaxer. The scalp protectant forms a protective barrier between the scalp and the relaxer, reducing the risk of skin irritation and burns.
