The indication that a barber's tool needs to be disinfected is when it is visibly dirty or has hair on it. This is crucial because the presence of dirt, hair, or any biological material can harbor bacteria, viruses, or other pathogens that pose a risk to the client’s health. Tools used in barbershops, such as clippers, scissors, and combs, must be clean to prevent infection and maintain hygiene standards.

Other conditions, like whether a tool is hot to the touch or made of stainless steel, do not determine its need for disinfection. A tool being new and unused may not require disinfection until it has come into contact with a client, but once it has been used, it is essential to properly clean and disinfect it, regardless of its new condition. Therefore, visible dirt or hair is a clear indicator that disinfection is necessary to ensure a safe and sanitary environment.
