The Quick & Simple: Henna is a flowering plant that’s been used to dye skin, hair, fingernails, leather, and wool for thousands of years. It’s actually a tall shrub (small tree) and grows natively in the tropical and subtropical regions of Africa, southern Asia, and northern Australasia in semi-arid zones. India commercially cultivates the most high-quality henna crops in the world. Henna is also used for temporary body-art tattoos. As a natural hair dye, it dates back over 6000 years: Cleopatra, Nefertiti, and ancient Romans used henna as a hair dye. More about Henna Here…
