What must a licensee use while performing salon services?

The correct choice emphasizes the importance of using porous wood implements in providing salon services. Porous wood implements are commonly used in various beauty services due to their ability to absorb moisture, which can help maintain sterility and cleanliness during procedures. They are also lightweight and easy to handle, making them practical for both salon professionals and clients.

In a salon setting, safety and hygiene are paramount, and the use of porous materials can contribute to a lower risk of transmitting infectious agents. Wood is a natural material that can be treated and sanitized as needed, aligning with health regulations that safeguard customer well-being.

On the other hand, while disposable plastic implements can be hygienic, they are not always the preferred choice depending on the specific service and environment. Metal utensils may pose a risk if not properly sanitized and are generally used in different types of procedures, such as those requiring sharper tools. Surgical tools are typically reserved for medical professionals in a clinical setting and are not appropriate for general salon use, as they require special training and higher standards of sterilization.
