All of the following require the use of gloves except:

Using gloves is a crucial practice in maintaining hygiene and safety during various cosmetology procedures. In the context of a plain manicure, the use of gloves is generally not required because the procedure typically does not involve exposure to blood or other potentially infectious materials.

During a manicure, the primary tasks are filing, buffing, and applying polish, which do not pose significant health risks for either the client or the cosmetologist. As a result, practitioners might choose to perform a plain manicure without gloves, relying on good sanitation practices for the tools and workspace.

In contrast, pedicure procedures, hair coloring, and waxing often involve more direct contact with skin and potentially hazardous chemicals or materials where gloves are necessary to protect both the cosmetologist and the client. This helps to prevent skin irritation, allergic reactions, or the transmission of infections.
