What is the typical pH range of hair products?

The typical pH range of hair products is crucial for maintaining the health and integrity of the hair and scalp. A pH range of 3.5 to 5.5 is ideal because it closely aligns with the natural pH of human hair and skin, which is slightly acidic. This acidic environment helps to keep hair cuticles closed, promoting shine, reducing frizz, and preventing damage.

When hair products are formulated within this range, they can effectively help in maintaining the moisture balance, reducing the likelihood of scalp irritation, and enhancing the overall health and appearance of the hair. A pH that is too high can raise the cuticles of the hair, leading to a rougher texture and potential damage over time, while overly low pH products can lead to hair becoming overly brittle and dry.

Thus, the most suitable pH range for hair products supports both their functionality and the maintenance of hair’s natural condition.
