Question: 1 / 400

What is the general pH range for acid-balanced shampoos?

3.0 to 4.0

4.5 to 5.5

The pH range for acid-balanced shampoos is typically between 4.5 to 5.5. This range is ideal because it closely aligns with the natural pH of the scalp and hair, which helps to maintain the health of both. Shampoos with an acid-balanced formula help to preserve the cuticle layer of the hair, reducing the risk of damage and ensuring that the hair remains smooth and shiny.

A pH lower than 4.5 might be overly acidic, potentially leading to dryness or irritation of the scalp and hair. Conversely, a pH above 5.5 could be too alkaline, causing the cuticle to lift and resulting in frizz or damage. Therefore, maintaining the pH within the range of 4.5 to 5.5 is crucial for optimal hair care, as it supports the overall balance of the scalp's natural oils and the integrity of the hair structure.
