I had electrolysis done between 2004 and 2008, on my face, chest and abdomen. No regrowth to speak of except maybe a few hairs, no more than 5, that are very thin, weak and barely visible, so hard to see in fact that I need a magnifying mirror to see them and it takes me forever to pluck them. Great job and a worthwhile investment. I started with laser but I'm glad I continued with electrolysis and did most of it with electro (i.e. thermolysis/flash).
