Where do you test the water temperature when performing a shampoo service?

• A. On your inner wrist
• B. On the back of the hand
• C. At the faucet
• D. On the elbow

Answer: (A)

Testing the water with the inside of the wrist is the best practice because the skin there is very sensitive to temperature, giving you a quick and accurate sense of whether the water is comfortably warm or potentially too hot before it reaches the client. This early check helps prevent burns or discomfort during the shampoo. The back of the hand or elbow is less reliable for feeling temperature promptly, and testing only at the faucet doesn’t guarantee the final mix will feel right on the scalp. So the inner wrist provides the most immediate, practical feedback for safe, comfortable shampooing.
