Which item is prohibited for use in a salon setting?

Using skin cutting equipment in a salon setting is prohibited due to safety and health regulations. These tools can create risks of injury, infection, and cross-contamination if not handled properly. Given that salons focus on cosmetic services rather than medical procedures, the use of items that could cut into the skin is generally against the guidelines established for beauty establishments.

In contrast, disposable razors, wooden applicators, and barber scissors serve specific, safe, and hygienic purposes. Disposable razors are often utilized for shaving purposes and are made to be used once to maintain hygiene. Wooden applicators are recommended for applying substances in a sanitary manner, and barber scissors are designed for hair cutting while adhering to safety protocols. Each of these items has its place and function within the salon environment, making them acceptable for use when proper sanitation and safety measures are applied.
