What effect does a pH balanced shampoo have on hair?

A pH balanced shampoo is designed to maintain the hair's natural acidity, typically falling in the range of pH 4.5 to 5.5. This is important because hair and scalp have a slightly acidic environment that helps to keep the cuticle tightly closed and healthy. When the pH is balanced, it can help prevent issues such as frizz, dullness, and damage, which can occur when the hair cuticle is lifted or if the scalp becomes too alkaline.

Maintaining the hair's natural acidity aids in preserving moisture and enhancing shine, while also safeguarding the hair from environmental stressors. This is especially beneficial after chemical treatments or sun exposure, ensuring that the hair remains in optimal condition.
