The 'pH' scale measures the acidity or alkalinity of a solution. In cosmetology, understanding pH is crucial because many hair and skin products are formulated to work effectively at specific pH levels. The scale ranges from 0 to 14, with values below 7 indicating acidity, values at 7 being neutral, and values above 7 indicating alkalinity. For instance, a product designed for oily hair may have an acidic pH to help clarify and balance the scalp, while a product intended for dry hair might be more neutral or slightly alkaline to provide moisture. Grasping how pH affects both products and the hair or skin's condition allows cosmetologists to make informed choices when selecting treatments or performing services.
