In General, good electrologists DO kill hairs with only one treatment. One will still need multiple treatments in the same area, because it takes 9 months for every hair to show itself at least once.
Because some hairs will not be in the right phase when the treatment appointment takes place, some will have to be removed in the next year, and will then have been treated twice, as will others that were not perfectly treated the first time. These hairs should be a minority of the hairs treated.

Because people are not paying close attention, and/or may not really understand all we would like them to when we do consultations, hair removal professionals often fudge the facts to say something that the client will actually understand and come to the idea that you need multiple treatment appointments and hope to have enough appointments to be able to hammer out a better understanding of the truth later.
A personal trainer would not want to spend time on the phone arguing, or trying to explain how or why elimination of all artificial sweeteners and substituting water for everything one had artificial sweeteners in would melt 20 pounds all by itself. If, however there was some excuse to get the person to try it, that fudge would be worth its weight in gold. Get it? <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
