Chemistry of Mehandi (Henna): Natural Dyeing Mechanism, Composition, and Applications
Abstract: Mehandi (Henna), derived from the plant Lawsonia inermis, is one of the oldest natural dyes used for body art, hair coloring, and traditional medicinal applications. Beyond its cultural significance, henna represents an interesting example of applied organic chemistry, where naturally occurring molecules interact with biological tissues to produce long-lasting coloration. The primary coloring constituent of henna is Lawsone (2-hydroxy-1,4-naphthoquinone), a naphthoquinone compound responsible for the characteristic reddish-brown stain. When henna …
