Measuring pH in shampoo

Published 18. December 2015

Shampoo is a hair care product used for removal of dirt, dandruff, skin particles, oils and other contaminated particles.

As the scientists behind hair care progressed, manufacturers synthesized chemical additives for use in shampoo as fragrance, foaming agents, and colored dyes. Shampoo is now created and structured towards various hair types, as well as to achieve a certain end result, such as the reduction of dandruff or greasy hair. Both the synthetic and natural ingredients used in a shampoo dictate the pH of that particular product. The pH of a shampoo will alter the natural pH of skin and hair, which ideally falls between pH 3 and 5 and pH 4 and 5, respectively, thereby affecting their physical and chemical makeup.
