Electrolysis costs depend on a lot of factors, including how much hair needs to be removed, the size of the area being treated, and where you get your services performed.  Generally, a large city is going to have higher rates than a small town.  For the best results, follow the electrologist's recommendations in scheduling appointments.  For areas that have been waxed or tweezed, treatments will be more frequent than for areas that have been shaved.
