Which items are prohibited from use in a salon?

The correct choice highlights the importance of maintaining hygiene and safety standards in a salon setting. The use of certain items, such as cellulose sponges, styptic pencils, and non-disposable power puffs, is prohibited because they can harbor bacteria and pose a risk of cross-contamination.

Cellulose sponges are porous and difficult to sanitize completely, potentially leading to the spread of infections. Styptic pencils, although useful for stopping bleeding, may also present sanitation issues if they are reused. Non-disposable power puffs can similarly trap bacteria unless they are properly disinfected after each use, which is often challenging in practice.

By focusing on the requirement for sanitary, single-use items, the regulations aim to ensure that clients receive safe and clean treatments, thereby protecting their health and minimizing the risk of infection in a salon environment.
