Shampoos that are pH balanced include DHS Clear Shampoo for Daily Cleaning of Hair & Scalp, the majority of shampoos by Head and Shoulders, all Suave shampoos, and many products in the Herbal Essences, Pantene, and Tresseme lines. And there are many, many more.
Choosing a pH balanced shampoo can improve the healthiness and appearance of hair.
Shampoos and other hair products use the chemistry behind alkali and acidic substances to expand and contract the hair shaft, producing varying results to hair's appearance. In chemistry, pH is a measure of acidity. Anything lower than 7 on the pH scale is said to be acidic, while anything higher is alkaline. Water has a pH level of about 7.
Human skin and hair are between 4.5 and 5.5 on the pH scale, making them slightly acidic. A pH balanced shampoo will prevent hair from becoming either too soft and easily penetrable (a product of alkali substances), or too hard (a product of acidic substances).
In general, some hair care lines carry a variety of pH balanced shampoos, while others make specific products designed to achieve pH balance. Whether the entire line is pH balanced or just one or two products, all are easily found in the local drug store.
