Which type of pH would be considered neutral?

A pH level of 7 is considered neutral because it is the point at which the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution are equal. This balance means that the solution is neither acidic nor basic. In the pH scale, values below 7 signify acidity, with lower numbers representing stronger acids, while values above 7 indicate alkalinity, with higher numbers representing stronger bases. Understanding this concept is crucial in cosmetology, as products used for hair, skin, and nails often have specific pH ranges that can affect their performance and the health of the client’s hair and skin. Maintaining a neutral pH is often desired in cosmetic formulations, especially those intended to cleanse or treat the skin, as it minimizes irritation and promotes skin health.
