Change gray hair to black using coffee and indigo powder in a natural way.

Put on a shower cap to protect your hair and prevent it from staining your sheets. Leave the mixture on your hair overnight so the color can fully develop.
Wash thoroughly.

In the morning, wash your hair with warm water. Don’t wash your hair with shampoo right after rinsing out the dye so the color can stay longer.

To achieve the best outcome, do something again.
