Which of the following is NOT required on a client's service record?

The correct answer indicates that a client's payment information is not required on a client's service record. In the context of Texas cosmetology laws and rules, maintaining a service record is essential for tracking the services provided to the client, including details that can affect health and safety, such as the date of the service, the specific service type performed, and the products used during the appointment. These records help ensure proper hygiene and safety protocols are followed, as well as facilitate communication and continuity of care between different visits.

However, payment information is considered sensitive and private, and there are no specific requirements mandating that it must be recorded as part of a service record. Keeping the service record focused on the services and products used rather than financial transactions also aligns with best practices in client confidentiality and data protection. Thus, the inclusion of financial details is not necessary within a client's service record as per Texas state regulations.
