All of the following require the use of gloves EXCEPT?

Wearing gloves is a crucial safety and hygiene practice in the salon and spa environment, helping to protect both the technician and the client from potential contamination and infections. In the context of a plain manicure, the service typically involves the trimming and shaping of nails, buffing, and application of nail polish. This procedure is generally considered low-risk in terms of exposure to bodily fluids or hazardous materials, which is why gloves are not universally required.

Conversely, nail enhancement applications and pedicure services involve more direct interaction with the skin and nails, where there is a higher risk of exposure to bacteria or fungal infections. Therefore, gloves are necessary to maintain hygiene in these procedures. Similarly, facial waxing involves the potential for skin irritation and exposure to delicate facial skin, making the use of gloves essential for protecting both the client and the technician.

Thus, the use of gloves during a plain manicure is not as mandatory compared to these other services, leading to the conclusion that it is the exception in this scenario.
