All of the following information could be found in client records EXCEPT:

• A. Date of Last Service
• B. Price of the Service
• C. Client's Social Security Number
• D. Technique and Application Method

Answer: (C)

Keeping client records focuses on information that helps you deliver consistent service and manage the appointment history. The date of the last service is useful because it shows how recently the client visited, helping with follow-ups, scheduling, and tracking loyalty or frequency. The price of the service belongs in billing and revenue tracking, ensuring you have a record of charges for each visit. The technique and application method notes are important for reproducing a style in future visits, especially if multiple stylists work with the client or if you need to remind yourself of the exact steps used previously.

Social Security numbers are highly sensitive personal data and not needed for daily salon service. Storing such information poses privacy and security risks and isn’t standard practice in client records.
