What does the term "pH" stand for?

The term "pH" stands for "Potential of Hydrogen." It is a measure of the acidity or alkalinity of a solution and reflects the concentration of hydrogen ions present. A low pH indicates a high concentration of hydrogen ions, meaning the solution is acidic, while a high pH indicates a lower concentration of hydrogen ions, making the solution more alkaline.

Understanding pH is crucial in the cosmetology field because it affects the condition of hair and skin products, determining how they interact with different hair types and skin conditions. For example, hair products with a pH balanced to that of the hair (around 4.5 to 5.5) help maintain the hair's natural moisture and prevent damage. Recognition of pH levels helps cosmetologists choose the right products for their clients to achieve desired results safely and effectively.
