Black can be a 1, or a 2 step process. It comes with 1 pack of pure henna, and 1 pack of pure indigo. It will come with directions how to make black 3 different ways. If you have never used it, the only way to figure it out is to try the easiest way first. For a jet black, usually, the 2 step rule will apply, but some can use indigo by itself and achieve jet black. You can try a small area prior to the full application to see how your hair reacts. Keep in mind the 2 step is extremely rewarding and conditioning to your hair. Ingredients
