Performing a patch test for allergies is essential before using chemical products on a client's hair or skin. This procedure helps identify any potential allergic reactions to the chemicals that may be used during the service. Chemicals in hair dyes, relaxers, or other treatments can sometimes cause skin irritations or allergies, so a patch test, which typically involves applying a small amount of the product to a discreet skin area, allows the barber to ensure the client will not have a negative reaction.

In the context of the other choices, while discussing service duration, getting parental consent for minors, and conducting a hair texture analysis could be important parts of the client consultation process, they do not directly address safety and allergy concerns related to chemical usage. Ensuring the client's safety by identifying allergies should be the primary focus, making the patch test a necessary and prudent step before proceeding with any service that uses chemicals.
