What is the standard pH level range for hair products?

The standard pH level range for hair products is 4.5 to 5.5. This range is optimal for maintaining the health and integrity of the hair and scalp. Hair and skin have a natural acidic pH, which helps protect against damage and bacteria. Products formulated within this pH range are less likely to disrupt the hair cuticle, helping to keep hair smooth, shiny, and manageable. Maintaining this balance minimizes the risk of dryness or irritation, ensuring that hair remains in good condition after use.

Products outside of this pH range can lead to issues such as cuticle lifting, which can cause frizz, dullness, and increased susceptibility to damage. Hence, understanding the importance of pH in hair care is crucial for both the effectiveness of the products and the overall health of the hair.
