What should be done prior to performing a permanent wave service?

Before performing a permanent wave service, it is crucial to examine the scalp. This step is essential because it allows the cosmetologist to assess the condition of the scalp and hair. By examining the scalp, a practitioner can identify any issues such as irritations, open wounds, or scalp conditions that could impede the service or cause harm to the client. This assessment helps ensure that the chemical process of a permanent wave is safe and appropriate for the client's hair and scalp condition.

Furthermore, evaluating the scalp is also part of a larger consultation process that should include discussions about any previous chemical treatments or allergies that may affect the service outcome. This foundational step enhances overall safety and effectiveness, ensuring that the client receives a service tailored to their specific needs.
