Bests & Worsts Reviews from Amazon

"When carbon dioxide dissolves in water about one-percent of it forms carbonic acid, which almost immediately dissociates to bicarbonate anions and protons. Despite its fleeting existence – about 300 nanoseconds – carbonic acid is a crucial intermediate species in the equilibrium between carbon dioxide, water and many minerals. It plays a crucial role in the carbon cycle – the exchange of carbon dioxide between the atmosphere and the oceans – and in the buffering of blood and other bodily fluids. The short life span of carbonic acid in water has made it extremely difficult to study." This shampoo is made with something else since carbonic acid is completely unstable at room temperature, so how can I buy a product with what appears to be false advertising?
