Henna
Henna is a dye made from dried, powdered leaves of Lawsonia inermis, used to produce reddish stains used in body art. It originates in North Africa and the Middle East, and has been used since at least antiquity across the region, including in ancient Egypt, as well as in ancient Mesopotamia and broader pre-Islamic Arabian cultures, as a hair and body dye, notably in the temporary body art of mehndi resulting from the staining of the skin using dyes from the henna plant. After henna stains reach their peak colour, they hold for a few days and then gradually wear off by way of exfoliation, typically within one to three weeks.
