Please note: this is a different product to Indigo Dye Powder
The indigo plant has a long history of use as a natural dye for hair and textiles. Indigo leaves contain a substance called Indigotin which has a deep, denim blue colour. However, the leaves must be processed in order to extract this pigment.
Indigo gives a natural violet/blackish colour to hair and is often used in combination with Henna to create different shades of brown and black. It is safe and can also be used as a green colourant for cold process soap.
This product is for external use only.
