What type of electrodes does a high frequency machine use for facial and scalp treatments?

Glass
Metal
Plastic
Rubber

The correct answer is: Glass

A high frequency machine typically uses glass electrodes for facial and scalp treatments. Glass electrodes are commonly used with high frequency machines because they are non-reactive, easy to clean, and allow the current to pass through while not harming the skin. Metal, plastic, and rubber electrodes are not suitable for high frequency treatments because they may not conduct the current effectively or could potentially cause harm to the skin. Therefore, the correct answer is A.
