When a client suddenly does not feel anything during treatment, what should you check first?

When a client suddenly does not feel anything during treatment, checking the needle cord first is essential because the needle is the primary tool used in electrolysis to deliver the current to the hair follicle. If the needle or its connection is compromised, such as being disconnected or damaged, it can result in a lack of sensation for the client since the current may not be properly delivered. Ensuring the integrity of the needle cord is crucial for effective treatment and maintaining client safety.

While other factors like machine settings, the client’s comfort level, and skin condition are also important to assess, the immediate concern lies with the functionality of the needle since it directly affects the treatment process. If the needle is not working correctly, addressing other issues would be unnecessary until that core component is verified and fixed.
