Shampoo bars, not soap

Why is this important?

The most important difference between a soap and a shampoo is the pH (which stands for potential of Hydrogen), or how acid or alkali a product is.

The natural pH of the skin is between 5 and 6. If any type of product differs very much from this range it is not good for the skin and hair. Why?

Soap is an alkali and typically has a pH of 8 to 9, which is fine for skin because sebum, the natural oil of the skin which is acidic, quickly spreads over the skin and brings the pH down to normal..

But this oil takes much longer to spread over the hair, meaning that the pH of the hair is alkali for much longer. The effect of this is to swell the hair making it dry, dull and weak which leads to breakage.

EarthKind® Shampoo Bars have a pH between 5 and 6, which compliments the hair’s natural pH and natural beauty.

The science behind it
