Is it permissible for an operator to leave a client during a permanent wave process?

The answer is that the operator must remain with the client during the permanent wave process because the procedure involves chemical treatments that can have potential risks. The presence of the operator is crucial for monitoring the client's safety and the effectiveness of the treatment. Chemicals used during a permanent wave can react unpredictably; thus, it is essential to ensure that the client is properly attended to at all times. Leaving a client unattended could lead to adverse reactions, improper processing, or harm due to accidental negligence.

In addition, regulations set forth by the Pennsylvania State Board of Cosmetology emphasize the importance of client care and safety, highlighting that operators should adhere to best practices at all times. This ensures not only the health and safety of the client but also the professionalism and credibility of the cosmetology practice.
