What is considered the least acceptable method for removing loose hair after a haircut?

The least acceptable method for removing loose hair after a haircut is using an unsanitized neck duster. This method is inadequate because hygiene is paramount in any barbering practice, and using unsanitized tools can transfer bacteria and other contaminants from one client to another. An unsanitized neck duster can harbor dirt, oils, and hair from previous clients, which poses a risk of infection or irritation.

Proper hygiene practices, including using sanitized tools and equipment, are critical to maintaining a clean and safe environment for clients. Other methods, such as using a sanitized neck duster, brushing the hair, or using a dryer, are considered acceptable because they help ensure that loose hair can be removed in a safe manner that protects client health and comfort.
