What is the pH range of acid-balanced shampoos?

Acid-balanced shampoos, which are designed to maintain the natural pH of the hair and scalp, typically have a pH range of 4.5 to 5.5. This acidity level is important because it helps to close the hair cuticle, promotes shine, and minimizes frizz. Additionally, an acid-balanced formula works effectively with the natural oils and moisture of the scalp, ensuring that the hair remains healthy and well-conditioned.

Products outside this pH range—especially those that are more alkaline (higher pH)—can disrupt the hair's natural balance, leading to issues like dryness and damage. Conversely, overly acidic products can also cause irritation or damage. Therefore, maintaining a pH within the 4.5 to 5.5 range is essential for optimal hair health and functionality of the shampoo.
