electrolysis for beard reduction what to ask

Ready to start the contacting phase of my beard reduction electrolysis journey and am wondering what important questions I should be asking in order to maximize successful treatment? I know Thermolysis or Blend will give me the fastest/best results but what else should I be asking? I was kinda hoping to stumble upon a recommended practitioner in the south jersey/philadelphia area but unfortunately most of the recommended professionals are a bit of distance away from me unfortunately. Might look into mega sessions down the road but regardless i’m going to have to start local.
