Shampoo pH influences how the cuticle feels after cleansing. Alkaline formulas can raise or swell the cuticle, while mildly acidic formulas tend to leave hair smoother.

pH is only one part of a shampoo's behavior. Surfactant choice, conditioning system, water hardness, and wash frequency matter too.
