What must cosmetologists do before applying products to a client?

Before applying products to a client, performing a patch test is an essential practice, especially when it comes to hair color, chemical relaxers, or any other products that may cause adverse reactions. A patch test involves applying a small amount of the product to a discreet area of the client's skin, typically behind the ear or on the inside of the elbow, to check for any allergic reactions or sensitivities. This precaution helps ensure the safety of the client and prevents potential harm from using a product that may not be suitable for their skin type or condition.

Conducting a patch test aligns with industry best practices and regulatory standards, as it emphasizes the importance of client safety and satisfaction within the cosmetology profession. This step reflects a commitment to responsible application of products, where the health and well-being of the client are prioritized.

While providing a full consultation, asking for verbal consent, and reviewing manufacturer instructions are also important steps in the process, the patch test specifically addresses the need to identify any contraindications prior to product application, making it a critical step in client care.
