When hairs are not treated completely - they often are partially treated. What I mean by that is that some of the hair follicle stem cells are destroyed, but not all. The result is smaller diameter hairs.
We used to describe treatments as working "piece-meal". That piece-meal destruction did get results, but treatments took longer.
If left untreated by electrolysis after a piece-meal destruction, the hairs could become coarse again, since hormones influence the hair follicle.
