What must a licensee use while performing salon services?

The correct answer emphasizes the requirements for sanitation and safety in a salon setting. Using porous wood implements is a common practice because they can be more easily cleaned and sterilized, thus minimizing the risk of infection or contamination. Porous materials can absorb liquids, making them suitable for absorbing disinfectants during cleaning processes.

In a salon environment, where the risk of cross-contamination is significant, the choice of implements is crucial. While other materials like metal utensils may also be used in certain contexts, they typically require strict cleaning protocols to ensure they are free from bacteria and other pathogens. Disposable plastic implements are often intended for one-time use, but they may not be as eco-friendly or versatile as wood options. Surgical tools, while precise, are not practical for everyday salon services and would not align with typical cosmetology practices. Therefore, wooden implements strike a balance between usability and hygiene during various salon services.
