Conducting a patch test before using new products is a crucial step when working with clients who have allergies. This test helps to determine if a specific product will provoke an allergic reaction or irritation on the client's skin. By applying a small amount of the product to a discreet area (usually the inner arm) and observing it for a specific duration, you can gauge the client's sensitivity to the ingredients without exposing them to a full treatment. This precaution not only protects the client's health but also fosters trust and demonstrates professionalism.

Using products without testing can lead to adverse reactions, which is particularly risky for clients with known allergies. Avoiding questions about allergies neglects the client's safety and does not allow for informed product choices. Relying solely on natural products may not guarantee safety either, as natural ingredients can also cause allergic reactions. Therefore, performing a patch test remains the most effective means of ensuring the well-being of clients who might be sensitive to certain substances.
