To style the hair

To check for allergic reactions

The purpose of a patch test in chemical services is to check for allergic reactions. This test is performed before applying chemical products, such as hair dyes or relaxers, to a client’s hair or scalp. It involves applying a small amount of the product to a discreet area of the skin, typically behind the ear or on the inside of the elbow, and observing for any adverse reactions, such as redness, itching, or swelling, over a 24 to 48-hour period.

Conducting a patch test is essential to ensure the client's safety and to prevent potential allergic reactions that could lead to discomfort or more severe health issues. By identifying any sensitivities beforehand, barbers and stylists can provide a more enjoyable and safe experience for their clients during chemical services.
