Which method is NOT recommended for a client with an active skin infection?

Electrolysis is considered a method that is not recommended for clients with an active skin infection due to the invasive nature of the procedure. Electrolysis involves inserting a fine needle into hair follicles to deliver an electrical current that destroys the hair root. If a client has an active infection, this technique could exacerbate the infection by introducing bacteria deeper into the skin and increasing inflammation or irritation in the affected area.

In contrast, while waxing, shaving, and laser hair removal may also present risks, they do not involve creating an open wound as directly as electrolysis does. Waxing removes hair from the root and can irritate the skin, but it's typically performed on intact skin. Shaving only affects the surface layer of skin, and laser hair removal, while it can cause some irritation, is generally regarded as a less invasive option than electrolysis. Therefore, in cases of active skin infections, avoiding procedures that can disrupt the skin barrier significantly, such as electrolysis, is essential for a client's safety and recovery.
