Indigo use alone (not recommended unless you want blue/blue hair) makes your hair blue/black when used AFTER you have henna'd. If you want a hair color of brown or auburn, you would mix some indigo in with your henna to lessen the red stain imparted by the henna.

I agree with January Noir, indigo has no effect on the henna's wonderful benefits. Indigo seems to be a plant that only contains blue dye, no conditioning properties by itself.
