As I posted in other threads, Tria worked very well for me (black hair).
https://www.susans.org/forums/index.php/topic,102684.0.htmlI purchased it in October 2010, and I do not have noticeable hairs in my legs, armpits and beard area. Still I see a few fine and long hairs growing. As my skin becomes darker and darker in summer, using Tria is not desirable, and I save those fine hairs for another round of treatment in the upcoming fall. I am going to use Tria every six months to remove those fine fine long hairs.
For the first year, I irregularly used it, as I am usually busy doing other jobs. A merit of Tria is that you can treat by yourself whenever you have leizure time. You not need to make reservation, waiting in doctor's office. And it is far less expensive than professional laser treatment, but it give the same results, at least to me.
Remember that you need to be patient. It may take several rounds of Tria treatment to see any noticeable reduction in hairs. In my case, it took more than 1 year.
