What is the best practice for using a neck duster?

Using a neck duster is primarily designed to remove hair clippings gently after a haircut. This tool is specifically made with soft bristles that effectively sweep away loose hair from the neck and shoulders of the client without causing any discomfort. It helps ensure that the client feels clean and comfortable after their haircut, making it a vital part of a barber's finishing touch.

Other options listed are not the intended or effective use for a neck duster. For instance, while cleaning clippers and brushing off the chair are important tasks in the barbering process, they do not pertain to the specific function of a neck duster. Additionally, applying styling products would require different tools altogether, as the neck duster does not serve any purpose in product application. Thus, the best practice for using a neck duster is indeed to gently remove hair clippings after a haircut.
