What does pH stand for in chemical terms?

pH stands for "potential hydrogen," which is a measure of the acidity or alkalinity of a solution. The pH scale ranges from 0 to 14, with lower values indicating higher acidity (more hydrogen ions) and higher values indicating higher alkalinity (fewer hydrogen ions). The term "potential hydrogen" refers to the potential or ability of hydrogen ions to affect the overall pH level of a substance.

In the context of cosmetology, understanding pH is crucial, as it impacts the formulation and effectiveness of various products, such as shampoos, conditioners, and skin care items. Maintaining an appropriate pH balance is essential for both the health of hair and skin, as products that are too acidic or too alkaline can lead to issues like irritation or damage.
