Which of the following duties is required of a licensed holder in cosmetology?

A licensed holder in cosmetology is required to comply with health and safety standards, which is vital for protecting both the clients and the practitioners. Adhering to these standards ensures that all procedures are performed in a safe and hygienic environment, preventing the spread of infections and promoting overall client well-being. This compliance is not just a best practice but is often mandated by regulatory authorities to maintain a consistent level of professionalism and care within the industry.

Health and safety standards cover a wide range of practices, including sanitation protocols, proper use of tools and equipment, and the application of products. By following these regulations, the licensed cosmetologist safeguards their clients' health and enhances the credibility of their practice.

While offering discounts, advertising, and employee licensing are important aspects of running a cosmetology business, they do not fall under the fundamental duties mandated by law. Instead, they can be considered as business strategies or practices that may vary across individual establishments.
