Biotic Herbs Indigo Leaf Powder is made from the leaves of organically grown Indigo (Indigofera tinctoria) plants. it is made by crushing the sun-dried leaves into a triple-sifted, microfine powder. When combined with Henna, this natural Indigo powder for hair will produce brown to black hues in your hair, making it a great alternative to chemical-based hair dyes. It effectively covers greys by depositing colour on the outer surface of the hair follicles. Apart from hair colouring, the Indigo powder cleanses the scalp gently and reduces the formation of dry flakes, thus combating dandruff and scalp irritation. It nourishes and strengthens hair from roots making hair strong and healthy from inside out.
