We manufacture high-quality indigo powder for hair coloring purposes. We have a lot of experience making this indigo powder in the last 25 years. We have a complete setup to make indigo. We make this powder from the leaves of the indigo plant which is called Indigofera tinctoria (scientific name), one of the oldest dyes known to humankind. It gives a very rich and deep blue shade to grey hair that long lasts.
Because of natural colour when we apply indigo to hair, it does not give deep color to hair. But after 24 hours its true color starts coming.
20 years ago, KEO was the first company to introduce indigo to use in hair coloring.
