Collagen: The most abundant protein in the human body that helps renew cells, improves the health of skin and hair and ensures the elasticity and regeneration of hair. PH BALANCE pH levels between 5 - 7 are ideal for shampoos and conditioners. The amount of hydrogen in the solution is what determines whether it is acidic or alkaline. Solutions with higher pH levels are harsher on hair and cause the cuticles to open, exposing the interior of hair shafts. Slightly acidic solutions work to close and protect the cuticles and in turn, help to retain moisture in the shaft.
