Which of the following is NOT a responsibility of a barber?

The responsibility of offering medical advice is not typically associated with the role of a barber. Barbers are primarily trained to provide grooming services, such as cutting and styling hair, as well as offering advice on hair care and proper grooming techniques. Their expertise lies in enhancing their clients' appearance and knowledge about personal care, rather than diagnosing or treating medical conditions.

While barbers may encounter a variety of clients and could provide general advice on hair maintenance and styling techniques, providing medical advice goes beyond their professional training and expertise. It's important for barbers to refer clients to qualified medical professionals for any health-related inquiries, especially those involving scalp conditions or skin issues, to ensure that clients receive appropriate care.
