A licensee cannot perform services on a client who has which condition?

The correct answer is based on the understanding that estheticians have a responsibility to ensure the safety and health of their clients, which includes assessing any conditions that may pose a risk of spreading infections or illnesses. A contagious condition, such as lice, directly interferes with this responsibility.

When a client has a contagious condition, it can easily spread to others, including the esthetician and other clients in the establishment. This makes it crucial for a professional to refrain from providing services until the condition is resolved.

Understanding the nature of contagious conditions is key; they are diseases that can be transmitted from one person to another, either through direct contact or indirectly through shared tools and equipment. In contrast, conditions like dry skin or minor cuts, while they may require special attention or care during treatment, do not pose the same level of risk to others as contagious conditions do. Allergic reactions can vary widely in severity and may be managed with the appropriate precautions, but they do not inherently involve the same risks of transmission as contagious conditions.
