What should barbers do before introducing new chemicals to clients?

Before introducing new chemicals to clients, barbers should perform a patch test. This practice is crucial for ensuring the safety and well-being of clients. A patch test involves applying a small amount of the new chemical product to a discreet area of the client's skin to monitor for any allergic reactions or sensitivities. This step helps identify potential adverse reactions before the product is used more extensively, thereby minimizing the risk of skin irritation or other negative effects.

Choosing to perform a patch test reflects a commitment to client safety and professional standards in the barbering industry. It's not only about caring for the client's immediate needs but also about building trust and confidence in the services provided. This proactive approach demonstrates that the barber is knowledgeable about chemical usage and is dedicated to maintaining a safe environment for their clients.
