The typical pH level of human hair ranges from 4.5 to 5.5, making this option accurate. This slightly acidic range helps to maintain the hair's health and strength. The acidity plays a crucial role in keeping the cuticle, the outer layer of the hair, smooth and closed. A pH level within this range also supports the natural oils produced by the scalp, which are essential for moisturizing and protecting the hair.

When the pH level of hair care products is higher than this range, it can cause the cuticle to lift. This phenomenon potentially leads to issues such as dryness, frizz, and increased susceptibility to damage. Products with a pH that falls within the typical range are more likely to preserve the hair’s natural condition and overall balance.

Understanding that hair is naturally acidic emphasizes the importance of selecting appropriate hair care products, including shampoos and conditioners, that align with this pH range to ensure optimal hair health.
