The term "pH" refers specifically to the acidity or alkalinity of a product. In cosmetology, understanding the pH of various products is crucial, as it directly affects the health and condition of hair and skin.

A product's pH level indicates whether it is acidic (pH less than 7), neutral (pH equal to 7), or alkaline (pH greater than 7). For example, hair care products often strive to be slightly acidic (around 4.5 to 5.5) to maintain hair health, as hair itself has an acidic nature. Using products that are too alkaline can lead to hair damage and an imbalance in the scalp's natural oils.

Moisture content, color, and viscosity are unrelated to the pH level. While moisture is important for the efficacy and experience of a product, it doesn't reflect its pH. Color pertains to the visual aspect of a product, and viscosity relates to its thickness or fluidity. Therefore, recognizing that pH indicates the balance of acids and bases in a product is vital in making informed choices about product application and effects on hair and skin.
