What should a cosmetologist do before performing a chemical service?

Before performing a chemical service, it is essential for a cosmetologist to conduct a thorough consultation and a patch test. This practice ensures that the professional assesses the client's hair type, condition, and any previous chemical treatments, as well as understanding the client’s needs and preferences. The consultation also allows the cosmetologist to explain the process to the client, addressing any concerns and ensuring that they are well-informed about the service.

The patch test is a critical step to identify any potential allergic reactions to the chemicals that will be used during the service. By applying a small amount of the product to a discreet area of the skin, the cosmetologist can observe for any adverse reactions over a specified period. This proactive measure helps ensure the safety and satisfaction of the client, minimizing the risk of unexpected complications during the chemical service.
