Indigo powder is a natural dye obtained from the crushed leaves of the indigo plant, which is a small shrub native to Asia and parts of Africa. It is used as a natural hair dye to color hair brown to black and is gentle on the hair compared to synthetic hair dyes. Indigo powder is produced by soaking the leaves of the plant overnight in water, which turns the water into a sluggish blue mixture. This mixture is then sun-dried until all the leaves completely dry up and become crisp. Once the leaves are dried, they are grounded to obtain the indigo powder. Indigo powder not only improves hair color but also soothes the hair scalp and follicles, offering a cooling and refreshing sensation that makes you feel relaxed and calms the body and mind. It is also a natural remedy to reverse premature greying of hair and strengthens the hair follicles. Indigo powder is usually used in combination with henna powder to create brown to black tones naturally, and it is always used with henna. It should not be used alone because it can possibly give a green hue to the hair.
