How To Cover Gray Hair With Henna: A Complete Guide

Gather the ingredients you may need. They contain:

  • 1-2 tablespoons black tea leaves
  • 2-3 tablespoons henna powder (adjust the amount)
  • 2-3 cups of water
  • ½ teaspoon lemon juice
  • Applicator Brush:

  • An old T-shirt

Step 1: Boil black tea leaves

Boil the black tea leaves in water for a while. Once it starts to bubble, let it simmer over low heat until the water is reduced by half. The water should be in proportion to the amount of henna powder you are using. Always use natural henna powder rather than those with a developer.

Step 2: Prepare a henna mask

Soak the henna powder in water for about 8 hours or overnight. Mix the henna paste, black tea and lemon juice. You can also add some amla powder to this mixture. However, this is optional.

Step 3: Apply the mask

Wear the old T-shirt to avoid staining and then part your hair. Use the applicator brush to cover the section from root to tip. Repeat with all hair sections. Wear a disposable shower cap to keep the hair intact and wait at least 30 minutes for the hair to absorb the paste.

Step 4: Wash it off

Rinse the paste with cold water. Make sure to wash thoroughly and apply conditioner to the hair. Do not shampoo immediately and let the color soak in. You can wash your hair the next day. You can apply henna once or twice a month.
