Calcium is essential for all living cells and plays a pivotal role in signal pathways and the maintenance of cell function.  Calcium is involved in the building up and the breaking down of metabolic products as well as the synthesis of hormones and membrane-dependant processes. Calcium is also responsible for transmitting information within a cell, cell development and cell growth.

Calcium has been shown to significantly impact the functional capabilities and development of the keratin cells that comprise the hair fibre and skin.
