What is the pH range of a pH-balanced shampoo?

The pH range of a pH-balanced shampoo is typically between 4.5 and 5.5. This range is significant because it is close to the natural pH of the scalp and hair, which helps to maintain the integrity of hair and scalp health. A pH-balanced shampoo effectively cleanses without stripping away natural oils or disrupting the scalp's natural flora. By keeping the pH within this range, the shampoo can help to prevent damage, frizz, and dryness, which can occur with products that have a pH that is either too low or too high. Maintaining this balance is crucial in professional hairstyling and care.
