Why a Slightly Acidic Scalp is Crucial for Hair & Scalp Health

Why Is Our Scalp Slightly Acidic?

pH, or "potential of hydrogen," measures how acidic or alkaline a solution is on a scale of 0 to 14. A pH of 0–6 is acidic, 7 is neutral, and 8–14 is alkaline.

Your scalp's natural pH falls between 4.5 and 5.5, making it slightly acidic. This delicate acidity is maintained by a protective layer called the acid mantle, which covers the skin and scalp. The acid mantle acts as a natural barrier, defending against bacteria, environmental damage, and maintaining a healthy scalp environment.

Choose Smarter, Safer Scalp Care
