A thermal sensitivity test is especially important for the client who has numbness or:

• A. Desensitized areas
• B. Hyperactive nerves
• C. Tingling sensations
• D. Normal sensation

Answer: (A)

Thermal sensitivity testing checks how skin responds to warmth so you can prevent burns during waxing. When a client has numbness or desensitized areas, the skin may not feel heat properly, so you can’t rely on their sensation to judge if the temperature is safe. The test helps you set a safe wax temperature and confirm the skin’s tolerance before you proceed. This precaution is especially important because reduced sensation increases the risk of overheating the skin.
