Which statement correctly describes where a thermal sensitivity test should be performed?

• A. It should be performed on the inside of the wrist or ankle
• B. It should be performed on the face
• C. It should be performed on the back of the neck
• D. It should be performed on the scalp

Answer: (A)

A thermal sensitivity test gauges how a client's skin responds to heat before applying heat-based hair removal. The inside of the wrist or the ankle is ideal because the skin there is thin and highly sensitive, allowing you to gauge tolerance safely and accurately without risking burns on more prominent or less forgiving areas. Areas like the face, back of the neck, or scalp have different skin characteristics or are harder to monitor for temperature, increasing the risk of an adverse reaction or uneven heat distribution, so they’re not suitable for the initial test.
