The best way to do electrolysis is to try to go for long sessions up front to get a full clearance. That way, you’ll only need to come in once a month or so to get another clearance and so on. You’ll have to do this about once a month for a year. If you can’t commit to this, you’ll likely need more hours overall because you won’t be treating hair in the first anagen phase of growth each time.
I recently discovered Absolutely Clear electrolysis in Manhattan around 13th Street and 6th Avenue. It’s very close to my house, so I got a couple touchups there with their good Apilus machine. Both ladies that work there are very good and their prices are reasonable for Manhattan. One of the ladies is actually often a speaker at conferences.
There are a bunch of others in Manhattan too, but I haven’t tried them. I tried two that I didn’t like. Arlene, who participates on this forum, is in Queens. Ihatebodyhair who posted above is in Jersey and has tried a few people around there.
You can go for consultations and see who you like best.
