Henna is a small flowering shrub which grows throughout the Middle East, South Asia and North Africa. As far back as human history has been documented this plant has been used to dye skin, hair and nails. The first observed usage goes back to ancient Egypt as archeologists have discovered mummified remains that have various body parts dyed with henna. A popular example of this is the mummy of Rameses II whose hair and nails are dyed with henna. Interestingly scientists have analyzed the hair of Rameses II and determined that his hair was originally red and they suggest that the use of henna as a hair dye was to perpetuate the reddish color of his hair in order to maintain a youthful appearance.
