What is the pH of the hair?

The nomenclature of pH refers to the hydrogen potential of the hair. This is maintained at values between 0 and 14, with number 7 being the well-known neutral pH. The rule of pH establishes that when it is above 7, we speak of an alkaline hydrogen potential. While it has a hydrogen potential below this figure, it is recognized as acidic.

This measurement is useful for making a calculation of the alkalinity or acidity of the components of the scalp and hair. This is a very large scale, even when it comes to making products for cleaning and hair care.

Hair pH and Scalp pH: Difference

A healthy scalp is one that maintains its pH between 5 and 5.5. Whereas for pH of the hair, it is recommended to keep it at a fixed number of 3.6.
