What must be done to ensure cleanliness before starting a haircut?

To ensure cleanliness before starting a haircut, it is essential to sanitize all tools and workstations. This step is crucial because barbers use various tools such as scissors, clippers, and combs that come into direct contact with the client's hair and scalp. Sanitizing these tools helps prevent the transfer of bacteria, viruses, and other pathogens that could lead to infections or other health issues.

Additionally, the workstation must be clean to create a safe and hygienic environment for both the barber and the client. A sanitized workstation minimizes the risk of contaminating tools and protects the overall health of clients. By addressing both tools and the workstation through sanitization, barbers uphold professional standards and promote client trust in the service provided.

Other choices may contribute to cleanliness in the barbershop, such as washing hands or wearing clean gloves, but they do not sufficiently encompass the complete sanitation process needed to ensure the highest hygiene standards before beginning a haircut.
