What must be kept by the salon owner regarding product testing documentation?

The requirement for the salon owner to provide a copy of product testing documentation to the model is rooted in the principles of safety and informed consent in cosmetology practices. Providing this documentation serves to ensure that clients or models are fully informed about the products being used on them, including any potential risks or reactions. This transparency helps build trust between the service provider and the client, enabling the client to make informed decisions about their treatment.

While keeping a copy for their records is important for the salon owner to maintain, this alone does not meet the legal obligation to inform the model. Sending documentation to state authorities is not commonly required unless specifically mandated by regulations, which is not the case in this scenario. Discarding all documentation after testing is contrary to the practice of maintaining accurate records and could potentially lead to issues if any reactions or problems arise related to the product used.

Thus, providing a copy of the documentation to the model aligns with best practices in the cosmetology industry and reflects a commitment to client safety and awareness.
