Viviscal PRO is a 100% drug-free, clinically proven dietary supplement that effectively promotes existing hair growth in women or men. Viviscal PRO is backed by over 25 years of research and development.The exclusive active ingredient in Viviscal supplements was first developed in the 1980s. A Scandinavian professor studying the Inuits discovered that their healthy hair and skin was the result of their fish- and protein-rich diet. The professor isolated the key protein molecules from their diet and it was from these origins that the marine complex AminoMar™ was created.
