What must all barbers provide to clients before the service begins?

Prior to offering any service, barbers are required to provide a detailed explanation of the service and its associated risks to their clients. This practice is vital because it keeps clients informed about what to expect during their appointment, including potential outcomes and any risks involved such as skin sensitivity to products, potential allergic reactions, or the implications of certain styles or treatments.

By ensuring that clients are fully aware of the specifics of the service they are about to receive, barbers not only promote transparency but also build trust and foster a professional relationship. This informed consent is an essential part of professional ethics in the barbering industry, reinforcing the importance of client comfort and safety.

While the other options might enhance the client experience in different ways—such as offering a promotional discount, providing checklists for service options, or creating personalized hair care plans—they do not fulfill the fundamental ethical requirement of informing clients about the service they are undertaking. Therefore, the necessity for a detailed explanation of the service and its risks stands as the most critical responsibility of barbers before commencing any treatment.
