Your hair possesses many properties. Factors such as color, appearance, texture, and healthiness of hair can be affected by these physiological properties. Here is a concept that you should try to understand when using products to treat and care for your hair. This is known as pH, which defines how acidic or how alkaline a substance is. pH is measured across various solutions in the body, such as on your blood, your stomach acids, and even the oils and sweat produced by your scalp. With this in mind, you can already surmise that pH can also affect the overall health of your hair.
