I have been using Rogaine successfully since 4/2013. In 9/2013, I started using Wen, specifically the Tea Tree formula. I noticed hair growth in the non-Rogaine areas! In 11/2013, I went to the Wen Forum on QVC and saw that many people have the same results. I started using one of the treatment oils and my results are consistent. I'm to the point where I'm reducing my Rogaine use in less obvious areas to see the results. For anyone with non-medical caused hair loss, I urge you to try Wen Tea Tree for at least 6 months. For additional info, check the QVC Wen forum.
