Henna dyes hair, skin, and fabric organically, similar to a black tea dye. Henna is extracted from a tree by drying and grinding leaves and stems. The greenish powder, when mixed with an acidic liquid, makes a temporary red, brown, or orange design on a porous surface. People use henna in ritual skin painting, called Mehndi, for birth and marriage celebrations. Western cultures have adopted henna to make temporary tattoos and organic hair dye.
I really like henna. Remember, henna is to be stored in a cool place, otherwise it looses its potency. Have fun!:)
