What should a cosmetologist inquire about before performing a chemical service?

A cosmetologist should inquire about the client’s medical history and allergies before performing a chemical service because this information is crucial for ensuring the safety and well-being of the client. Chemical services can involve products that contain strong ingredients, such as hair dyes or relaxers, which may cause adverse reactions if the client has specific allergies or sensitivities. Moreover, certain medical conditions can influence how a client’s hair or skin will react to these chemicals, making it essential for the cosmetologist to be informed.

Understanding the client’s medical history allows the professional to tailor the service accordingly, minimizing any risks of complications. This step is fundamental in establishing a safe and effective salon experience, ensuring that the treatment chosen is suitable for the client's unique needs. Seeking this information demonstrates a commitment to client safety and helps build trust in the client-provider relationship.
