This is an advertising pitch but it does make one excellent point. Hair loss is a direct result of calcification of the hair follicle. That is a biological effect that can be plausibly reversed somehow. This also provides a linkage between baldness and heart disease.
A google search shows many others are now following this trail. In the meantime, all this vindicates even scalp massages and other stimulation which can not possibly do enough but do help at least. They are merely on the right track.
It will narrow down to a biological imbalance combined with something to do with hair care as well with the biology been the biggest factor..
