Hair dye, a substantive, has been used for centuries as a cosmetic enhancer. It involves the application of pigments to change the natural color of hair to a desired shade.
Changing hair color has social, cultural, and personal significance. It enables individuals to express themselves, cover gray hair, or enhance their appearance. One notable historical development is the discovery of synthetic hair dyes in the late 19th century, expanding the range and accessibility of hair color options.
