What does low pH indicate?

A low pH value indicates that a substance is acidic. The pH scale ranges from 0 to 14, where values below 7.0 are considered acidic, 7.0 is neutral, and values above 7.0 are basic or alkaline. This understanding of pH is crucial in cosmetology, especially when working with products like shampoos, conditioners, and skincare items.

For instance, many haircare products are formulated with a low pH to help maintain the hair's natural acidity, which can benefit the hair by reducing frizz, enhancing shine, and improving overall health. Understanding that a low pH is indicative of acidity helps cosmetologists choose the right products for their clients based on specific hair and skin needs, aiming to provide optimal results.
