I had this done a while back. When I did it, I had it done once ever month or so or every 6 weeksish. The hair stays gone for about a month, then when it starts to grow back you need to go in again. They told me it would take about 6 treatments to work, but it didn't work for me. It still kept coming back. My doctor told me that some people just have to have it done every month or so. But it also treats people differently, I have really coarse dark hair, so that may be why. But for that month that I didnt have to worry about it, it was heaven! Hope it works out for you
