Conducting a patch test for allergies is a vital step before performing chemical treatments on the hair. This test involves applying a small amount of the chemical product to a discreet area of the client's skin, usually behind the ear or on the inner forearm, to check for any allergic reactions, such as redness, itching, or swelling. Recognizing potential allergies ensures the safety of the client and minimizes the risk of severe reactions, which could lead to discomfort or injury during the hair treatment.

The other steps, while important in maintaining hair health and achieving desired results, do not address the critical issue of safety that a patch test provides. Washing the hair thoroughly is beneficial for product application, but it does not assess skin sensitivity. Using a hairdryer to dry the hair and applying a protective serum can enhance the treatment process but should come after ensuring that the client will not have an adverse reaction to the chemicals being used. Prioritizing the patch test aligns with the best practices in the salon industry to protect both clients and professionals.
