I have also been thinning over the last several years. I even used Nioxin for the last 10. I recently saw a Naturopath, and she has me on a bunch of stuff. Not sure that is helping, but I also started using DS Labs this week and already have noticed less shedding. Not gonna lie, it is expensive stuff, but I have heard from many people that it works. Takes a while to see new growth, and haven't seen any yet (obviously since I just started it) but figure at least if it stops shedding so much I am halfway there! It is a 3-Step system, a Shampoo, Conditioner, and Treatment. and you have to apply the treatment twice per day. I have been following the regimen religiously. Good luck! Hair loss sucks and is so depressing!!! I feel ya.
