In cosmetology, what does pH stand for?

pH stands for Potential Hydrogen, which is a measure of how acidic or alkaline a solution is. In the context of cosmetology, understanding pH is crucial because it affects the health and appearance of hair and skin. The pH scale ranges from 0 to 14, with values below 7 being acidic, 7 neutral, and above 7 alkaline.

Hair and skin have a naturally acidic pH, usually around 4.5 to 5.5. When using hair care or skin care products, it is important that their pH levels are balanced to maintain the integrity of the hair cuticle and skin barrier. For example, overly alkaline products can strip hair of its natural oils and disrupt the skin’s barrier function, leading to dryness and irritation. Therefore, a strong understanding of pH and its implications in beauty treatments enhances the effectiveness of cosmetological practices, ensuring client satisfaction and health.
