When is a licensee prohibited from performing services on a client?

A licensee is prohibited from performing services on a client if the client has lice. This is because lice infestations are considered a communicable condition, which presents not only a health risk but also a sanitation concern for both the client and other patrons in the establishment. The presence of lice can lead to the spread of infection and may hinder the effectiveness of cosmetic services, as treatments may not yield the desired results when an infestation is present.

In contrast, a valid client license is not a concern when it comes to service provision, and a client’s request for a specific service does not inherently disqualify them from receiving services. Similarly, a client being late for an appointment, while it may affect scheduling, does not result in a prohibition against services. It's essential for licensees to maintain a healthy, safe environment, which is why addressing communicable conditions like lice is critical in a cosmetology practice.
