I simply recommend people "try the water and see how they feel".
That is the best testimonial.
As far as the "baldness" claims, I have seen people grow some hair and lose some grey or white. Needless to say if you are bald you are not going to grow a head of hair. I too would attribute any new growth or color change to a greater cleansing of their system and better hydration due to the water. Dehydration is one of the underlying causes of many afflictions people have today.
Been using hexagonal (or what is often called energized water) for almost two years and I would not go without it.
