First off, let’s just have a look at where you are right now. As I understand, you’ve had 5 weeks of electrolysis, with 2 hour sessions each week, totalling 10 hours. Now, that is quite a lot of electrolysis and the fact that the area is not yet cleared implies to me that either there is a lot of hair in the area/large area, or the electrologist is not working very fast (let me guess, about 3 to 5 hairs/min?), or a combination of both. There is nothing wrong with a Sterex machine but the Apilus electrologist may work faster. What is more important though, is which electrologist is actually killing follicles and that doesn’t depend on machine type.
It is difficult to advise you on what to expect without full and complete information on what sort of hair you are attempting to permanently remove, what you did to the hair prior to starting electrolysis, and information on how your electrologist is working.
Unless you are very fortunate, you will need to research and educate yourself about the electrolysis process. You should have some understanding of hair growth cycles and how electrolysis is performed to destroy follicles and what to look for in treatment - this will help you in selecting the right electrologist. Lots of people make the mistake of thinking they have a good electrologist but for the wrong reasons e.g. “I hardly get any reaction”, when in reality they have found someone who is not killing follicles (hence the lack of reaction) and then find hardly any progress is made after a year of regular sessions. The best way to do this is start reading through all the threads in the Professional Electrolysis forum reading back from today. In the discussions, you will find lots of questions and answers which will enlighten you on the relevant issues.
Personally, I think having a test patch done with any electrologist you are considering working with is the best way to proceed. Putting everything else aside, it will save you a lot of time and money if you establish whose treatment is actually killing follicles. I will link to a post about this below…
