What should barbers always do before applying a new product on a client?

Barbers should always conduct a patch test for allergies before applying a new product on a client to ensure the safety and well-being of the client. A patch test involves applying a small amount of the product on a discreet area of the skin, usually behind the ear or on the inner forearm, to see if there is any allergic reaction. This is particularly important because some clients may have sensitivities or allergies to certain ingredients in hair products, which can lead to adverse reactions such as irritation, rashes, or more severe allergic responses.

Conducting this test not only protects the client but also fosters trust and professionalism in the barber-client relationship. Ensuring that a product is safe for use before application is a fundamental practice in maintaining client safety and satisfaction in the salon environment. This proactive measure is essential in a field where personal care services directly affect a client’s health and appearance.

The other options, while important in their own right—for instance, washing hands is crucial for hygiene, discussing hair history informs treatment choices, and reading product labels is vital for understanding application and potential side effects—do not address the immediate need to assess allergy risk, which can have the most significant implications for client safety.
