Chin hair electrolysis pcod

Hello friends,
I am new here.i started my electrolysis session today on my chin hair.i have pcod with facial hair ( thick ) on my chin, sideburns and part of the neck.Just curious to know after how many sessions did you notice a visible difference in hair growth?.Were you able to stop electrolysis after getting desired results or is this a permanent thing for lifetime ?

Thank you so much
Good luck to you in your journey
