Indigo Hair Dye:
Indigo’s real name is indigofera tinctoria. In old times Greeks and Romans imported cakes of pigment called “indicum”, meaning “from India”, and this led to the term indigo.
Indigo is a plant that produces a dark blue dye which we all know as the colour used to colour blue jeans. It turns hair brown through to black when it is applied after henna. Even 100% grey hair goes brown or black when indigo is applied after henna . However, it will only ever stain the skin blue, not black. Its’ botanical family is : Fabaceae (Leguminosae). Its’ species is: Indigofera. Indigo molecules in the leaves of the plant contain the dye which oxidises to dark blue. They are alkaline. They react with henna which is acidic to create incredible dark shades with undertones of red, burgundy, orange, brown, and even stunning blue black. Note that alkalis and acids have different effects on the hair. Acids generally will harden and contract the hair, while alkalis generally will expand and soften the hair shaft. So henna and indigo go really well together and make a great team !

Our indigo hair dye contains only indigofera tinctoria. The green colour indigo dye powder is made by crushing and then sieving the dried leaves of the indigofera tinctoria plant. The powder is sieved multiple times to ensure the finest powder consistency. Nothing at all is added to the indigo dye powder. It is packed into a re-sealable poly bag and foil sealed straight after sieving to ensure freshness and potency.
