What should be done before applying hair dye to a client?

Apply conditioner first

Perform a patch test for allergic reactions

Before applying hair dye to a client, it is essential to perform a patch test for allergic reactions. This step is crucial for ensuring the safety of the client, as some individuals may have allergic sensitivities to certain ingredients commonly found in hair dye. The patch test typically involves applying a small amount of the dye to a discreet area of the skin, usually behind the ear or on the inner elbow, and observing for any adverse reactions. This precaution helps to minimize the risk of severe allergic responses, which can lead to skin irritation, rashes, or even more serious health issues.

Performing a patch test demonstrates professional diligence and reflects a commitment to the health and well-being of clients, which is a fundamental principle in the cosmetology profession. This protocol fosters trust between the stylist and client and ensures that the hair dye application can proceed safely.
