Mentioned in the Bible and used by the ancient Egyptians as a decorative cosmetic, henna is enjoying renewed popularity as an alternative to synthetic hair dyes.
There have been tomb findings of henna markings on mummies and some evidence of Bronze Age ritual use exists.
Made from the dried and powdered leaves of the Lawsonia inermis tree, henna starts out as green, but imparts a warm reddish-brown color. The active coloring ingredient is called lawsone. Henna can be mixed with coffee, indigo and other natural dyes
