I didn't find a forum about grey hair and reversing grey hair (food). Will it be added if people are interested. I would be interested in a forum about cold water therapy or even hydrotherapy (it contributes reversing grey hair), and a forum about fermented food, including kefir, kombucha and other stuff would be so great too! There's so many thinks to say about it! I suggest also a forum about Bates method to recover a good eyesight.
I don't know if cold water therapy is well known in your country, but in Europe, especially in France, a lot of people tried it to cure many ailments with sucess, there's a lot to say here and to experiment.
