The correct answer is: By conducting a paper test

Testing the heat of styling tools before use is crucial for both the clients' safety and the effectiveness of the styling service. The recommended method of testing the heat on a small section of hair or the inside of your wrist is effective because it provides a practical way to gauge the temperature without risking burns. The hair's sensitivity to heat allows you to assess if the tool is at an appropriate temperature for styling without causing damage. Similarly, testing on the inside of your wrist is beneficial because this area of skin is sensitive and can indicate the heat level without exposing hair to potential damage. Using a hard surface does not provide any relevant information about the temperature of the tool itself. Observing steam may indicate a high temperature, but it's not a safe way to determine whether a tool is suitable for use, as steam can also mean the tool is too hot and can cause hair damage. Lastly, observing the color of the tool is not a reliable method because color indicators can vary by manufacturer and do not directly correlate to the temperature. Thus, testing on a small section of hair or the inside of your wrist ensures that the tool is safe for use while maintaining the quality of the hair.
