Henna is a dye prepared from the plant Lawsonia inermis, also known as the henna tree, the mignonette tree, and the Egyptian privet,[1] and one of the only two species of the genus Lawsonia, with the other being Lawsonia odorata. Henna can also refer to the temporary body art resulting from the staining of the skin from the dyes. After henna stains reach their peak color, they hold for a few days, then gradually wear off by way of exfoliation, typically within one to three weeks. Henna has been used since antiquity in ancient Egypt and Indian subcontinent to dye skin, hair and fingernails, as well as fabrics including silk, wool, and leather. Historically, henna was used in West Asia including the Arabian Peninsula and in Carthage, other parts of North Africa, West Africa, Central Africa, the Horn of Africa and the Indian subcontinent. The name "henna" is used in other skin and hair dyes, such as black henna and neutral henna, neither of which is derived from the henna plant.[2][3]
