P3 Organic Indigo Leaves Powder is made from pure sun dried Indigo leaves of southern India, directly sourced from farmers. Indigo powder is mostly used to get the deep black hair or dark brown hair color but for the blonde, grey or white hair, getting black hair with indigo powder requires a two-step process. In this case, you first need to apply the pure henna to the hair that will dye your hair orange-red and then apply the indigo powder in the same way. This will give you the deep black color with wonderful shine. The color pigment in the indigo powder works really well with the orange color of the henna that is already present in your hair, otherwise you will get NO COLOR at all (on white or grey hair) or the lite bluish colored hair. If you apply the mixture containing both pure henna and indigo powder you will get different shades of brown depending on the ratios of each powder used. We strongly recommend use of P3 Organic Pure Natural Henna Powder along with this Indigo Powder.
