Natural Indigo Powder is used for coloring hair naturally without using any chemical. It shall be applied on henna dyed hair. These Indigo farms are maintained by SM Heena Industries. Indigo leaves are dried on cemented floor so apart from indigo plant stems and seeds bunch of cement particles also come as impurities in Indigo leaves. We first clean Indigo leaves and then grind it and make powder. Cleaning of indigo leaves make a huge difference in the quality of Indigo powder as the impurity level is very high in raw indigo leaves.
