Which of the following items would be appropriate to store in client records?

• A. Date of Last Service
• B. Client's Social Security Number
• C. Price of Service
• D. Hair Type

Answer: (A)

Tracking the last service date in a client’s file is essential because it creates a clear service history you can reference for future treatments, product recommendations, and scheduling follow-ups. It’s non-sensitive information that directly supports continuity of care and efficient planning. In contrast, storing a Social Security Number isn’t appropriate in client records due to privacy and security concerns and isn’t needed to provide services. The price of a service belongs in billing records, not the client history file. Hair type can be useful for tailoring services, but it’s not as universally required as a documented service date, and would typically be noted only as part of client notes. So, the date of the last service is the best fit for client records.
