What should a barber do if a client has a reaction to a product used during service?

When a client exhibits a reaction to a product used during a service, the best course of action is to discontinue use immediately and provide first aid. This response prioritizes the health and safety of the client, which is the primary responsibility of the barber or any professional in a customer service role.

Discontinuing use of the product helps prevent further irritation or the worsening of the reaction. Providing first aid ensures that the client receives appropriate care, which might involve cleaning the affected area, applying a soothing agent, or advising them to seek further medical attention if necessary. This proactive and responsible approach reflects professionalism and care for the client's well-being.

Continuing the use of the product, even with caution, poses risks as it may exacerbate the reaction. Asking the client to ignore the reaction is neglectful and can lead to serious consequences. Changing the product only for the next client does not address the immediate issue at hand and can lead to potential health risks for others as well. Always focusing on the client's safety and comfort is paramount in such situations.
