How To Check And Balance Hair And Scalp pH

What Is The pH Of Hair & Scalp

The natural pH of hair shaft is 3.67, while the scalp pH is 5.5. Attaining optimal pH levels is important for healthy and luscious strands.

Why Does The pH Of Hair Matter?

pH of the hair defines the quality of the locks. If the pH of the hair is pushed towards the alkaline side which is (above 7) it can expand the shaft making it prone to dryness, frizziness and damaged texture (what is hair texture). However, the acidic pH level (below 7) helps contract the hair cuticle preventing moisture loss. This doesn’t imply that using acidic substances for hair is harmless. In a nutshell, the pH of the hair defines hair strength, porosity (what is hair porosity), and the circumference of hair shaft.
