Where is the most appropriate place to test the temperature of heated wax?

Testing the temperature of heated wax on your wrist is the most appropriate option because the skin on the wrist is sensitive and reflects how the wax will feel on a client’s skin. The wrist provides a good balance between sensitivity and surface area, allowing for a reliable indication of the wax's temperature.

The forearm, while also a sensible choice, may not provide as immediate feedback as the wrist. The inner thigh is not recommended because it is a more private area and not practical for testing wax. Testing on the cheek could lead to potential irritation or discomfort, as facial skin tends to be more delicate and sensitive to heat. Thus, the wrist is the ideal location for ensuring the wax is at a safe and comfortable temperature for application on clients.
