Hello, after years of waxing and threading my face (primarily upper lip, lower lip and sometimes chin), I am now considering electrolysis as a permanent fix to my neverending problem of hair growth. But I am really scared after hearing stories of scabbing, scarring and other results from having the treatment done. I have a consult soon and might get a treatment done to see how things go. Is there anything I should do beforehand? I know about tea tree oil afterwards. Should I even get this done? Also, can anyone give me an approximate on how much I would be spending for these areas and how long it would take to finally be hair free? Any good recommendations for electrologists in toronto would help 
TIA
