Mondo Knows Facts
Hair shampoos are formulated slightly acidic to match scalp chemistry
Slightly acidic wash formulas protect the scalp's natural protective barrier
Healthy human skin and scalp possess a natural protective coating known as the acid mantle, with a pH between 4.5 and 5.5. Formulated hair shampoos maintain a slightly acidic balance to prevent hair shaft cuticle scales from swelling and roughening, keeping hair smooth and scalp microflora balanced.
