Stir henna with 50 degree hot water until you have a smooth paste. Then apply it evenly in your hair with a brush. If you only want to color your neck, spare lengths and tips.
Leave the organic hair color for about 30-120 minutes on your hair. The longer it is applied to your hair, the darker the color. To refresh the color, you only need 15 to 30 minutes. Then rinse with clear water.
