We make the powder from the Leaves of Indigo Plant, a sub-tropical shrub that stands 1 to 2 meters tall. Indigo possesses a Natural Blue Dye in its leaves that when used with Henna will dye your Hair in a range of colors from Reddish Brown, Light Brown, Brown, Dark Brown and Black. Indigo oxidizes when exposed to air and water. When the hair color is mixed with hot water for use, the dye is released. The indigo henna powder we offer is 100% natural. It gives strength, color as well as shine to hair.
