The primary purpose of a patch test is to determine sensitivity or allergic reactions to a product. This practice is crucial in the cosmetology field because clients may have different skin sensitivities and allergies to certain ingredients present in beauty and hair care products. By applying a small amount of the product on a discreet area of the skin, typically on the inner forearm, professionals can monitor for any adverse reactions such as redness, itching, or swelling, indicating an allergy. This step helps ensure the safety and suitability of the product for the client before proceeding with a full application, thereby preventing potential harm and promoting client trust.

Other options, while relevant in different contexts, do not address this critical safety aspect. Evaluating skill level, testing product fragrances, and assessing hair condition involve other types of assessments and are not related to ensuring that products used do not cause unwanted reactions in clients.
