What constitutes a "chemical service" in cosmetology?

A "chemical service" in cosmetology refers specifically to any procedure that involves the application of products designed to alter the structure of hair or skin. This includes services such as hair coloring, perming, relaxing, or chemical exfoliation for the skin, which change the chemical composition of the hair or skin itself to achieve a desired look.

Understanding these services is essential for practicing cosmetology, as they often require a deeper knowledge of chemical processes and safety practices to prevent damage to clients' hair or skin. For instance, when using hair color, a stylist must understand how the chemicals in the dye interact with hair fiber to effectively achieve the desired shade while maintaining hair integrity.

In contrast, simply washing hair with water, applying makeup, or styling hair does not engage in these chemical alterations; they are considered basic services that enhance appearance without restructuring the underlying materials. Thus, focusing on the depth of alteration involved in "chemical services" highlights the distinction between various salon practices.
