I would do a sample 15 min treatment with her and look for the following:
-do the hairs slide out without resistance after being zapped?
-does she use proper magnification?
-what method is she using to get you to your first clearance? how’s her speed?
-how does your skin look post-treatment and how does it heal (given proper aftercare of course)
Electrologists are often wary of giving precise numbers when it comes to treatment completion because there are just too many factors involved, that don’t necessarily depend on them. however, in most cases, if they do give a number, THEY will be the ones who will get blamed if you’re not finished by then. These factors involve how consistent you are in your treatments and committed to getting a bunch of treatments up front to clear the area (better with thermolysis btw at this stage, even if you switch to galvanic afterwards when you know for a fact you’re treating just the anagen hair that just came out), underlying medical conditions, etc.
