Conducting a patch test on a small area of skin is essential before using any new chemical product in a service because it serves as a preliminary safety measure. A patch test helps identify potential allergic reactions or sensitivities that a client may have to the chemical ingredients in the product. This step is crucial in preventing adverse reactions, which could range from mild irritation to severe allergic responses.

Performing a patch test allows you to assess how the client's skin reacts to the product without exposing them to the full treatment. It's a fundamental practice in ensuring client safety and comfort during cosmetic services, as it mitigates risks associated with chemical usage.

Reading the instructions carefully is also important to understand how to properly use the product, but it does not ensure the client's skin will tolerate it. Mixing it with previous products or applying the product directly to hair without testing poses a higher risk of adverse effects, highlighting why a patch test is the best initial procedure when introducing new chemical products.
