Which of the following is not true regarding electrolysis and contagious conditions?

Electrolysis is not universally safe for all conditions, particularly when considering contagious or infectious situations. There are specific skin conditions, especially those that are active and contagious, that can pose risks for both the client and the practitioner if electrolysis is performed. For example, if a client has a viral or bacterial infection, the procedure can potentially spread the infection or lead to complications. Therefore, practitioners should be trained to recognize these conditions and understand that electrolysis should be avoided in such cases, reinforcing the importance of a thorough health assessment before treatment.

The other options highlight essential practices in electrology; avoidance during outbreaks prevents complications, sterilization practices safeguard both client and practitioner, and assessing a client's health before treatment is key to ensuring safety and efficacy.
