It also means the scalp stays at its natural pH. When a shampoo has a pH higher than that, it “may increase the negative electrical charge of the hair fiber surface and, therefore, increase friction between the fibers; this may lead to cuticle damage and fiber breakage,” according to a study on the pH of hair products.

Why should shampoo not be too acidic?
