What is the purpose of performing a thermal sensitivity test in this context?

• A. To identify the safe testing site on the body (inside of the wrist or ankle)
• B. To determine hair color
• C. To evaluate muscle tone
• D. To check blood pressure

Answer: (A)

A thermal sensitivity test is about checking how the client’s skin reacts to heat before applying wax. Its purpose is to identify a safe testing area and confirm that the temperature is tolerable, helping to prevent burns or irritation during the service. The inner wrist or ankle are chosen because the skin there is thin and sensitive, making any heat reaction easy to see and assess. This step keeps the treatment safer by ensuring the temp won’t be too hot for the client. It’s not used to determine hair color, assess muscle tone, or measure blood pressure.
