I think it's a perfectly good question. The field of electrology has no professional or training standards so in the poorly trained hands, one could could experience electrolysis going on for years in the same treated areas and experience rapid fire plucking as I like to call it instead of effective treatment.
It takes many hours of training, proper understanding of the science of electrology and proper magnification(surgical loupes) to create a good electrologist. Without these things, an electrologists' kill rate ( amount of hairs that go permanently each session) will decline rapidly.
I recall another situation with a client who had previous electrolysis at a spa by a lady who also did nails, massage, and facials. My client had spent 6 months doing an hour every two weeks with no improvement. The longer a electrologist spends mastering the skill of electrolysis, the better. Therefore, finding an Electrologist who does electrolysis most of the time is really important.
I think a lot of people want quality work to be in the same vacinity as cheap and fast work. It is very difficult to find all 3 in most circumstances but proper electrolysis treatments can overlap those concepts. Electrolysis can be cheaper and work much faster than laser and if the electrologists kill rate is high ( at least 65% per session), then you've got quality in the bag too!
