When it comes to natural hair color, henna hair dye is probably the safest form of hair dye you can use. It even has some healthy benefits for your hair!

After posting 6 Things You Should Know Before Using Henna Hair Dye, a common question I receive is how henna hair dye works for covering gray hairs. Considering the fact that I work full-time and have two kids… I’ve definitely earned a few gray hairs. So, I figured I would try it out myself and report back.

Before you dive into using henna dye on your hair, it’s important to know that not all brands are created equal. Soon after I tried using henna hair dye for the first time, I had a hair stylist tell me that I could NOT use permanent dyes on my hair until the henna grew out, because some henna brands use chemical additives that can actually “burn” your hair when you use chemical dyes over them.

Luckily, that’s not the case with Morrocco Method’s henna hair dyes, because their hair colors are made with 100% pure plant dye. There are no chemicals, metallic salts, or PPD added. They still recommend waiting 6-8 weeks after dying your hair before using henna hair dye, to allow your hair to detox from the chemical dyes.

You might also want to wait 6-8 weeks AFTER dying your hair with henna before attempting to use chemical dyes again, because the results could be unpredictable. Plant dyes don’t lift easily out of your hair and the chemical color will fade faster because henna makes your hair less porous and absorbent.

Think of henna as a permanent hair dye, just so you know what kind of commitment you are making.

How to Cover Gray Hair with Henna Hair Dye

After talking with the folks at Morrocco Method about my previously bad experience using henna hair dye, they were super-helpful in teaching me how to properly cover up gray hairs (and even highlights) using 100% natural henna hair dye. If you’ll recall, last time I dyed my hair with a different brand, my blonde highlights turned bright orange, so my hair didn’t look very even in color. (I was hoping for a more even brown color at the time.)

This time, I did it the right way, and I’m super pleased with the results.

Before trying this hair dye, I had highlights added to my hair for a wedding (I was a bridesmaid, so lots of photos!), and the stylist stripped out a little TOO much color from my hair, if you ask me.

So, this hair dye test was perfect timing, because I wanted to see how much the henna could even-out my hair color and cover up the strands that had very little color to them. (I have a few real gray hairs around my scalp area, too.)

Covering up gray hair with henna dye is a two step process.

  1. First, you give the gray hair some color by using a red henna dye.
  2. Then you can use any other color you like over that red to achieve your final desired hair color.

Keep in mind that when using henna hair dye, you can only go darker in color. Like many boxed dyes, henna won’t lighten your hair. Morrocco Method does offer a blonde henna hair dye for people who already have blonde hair and want to use henna for shinier, healthier hair without going darker, but it won’t lighten your hair if it’s already dark.

IMPORTANT: When using a 100% natural henna hair dye, the preparation process can take up to 12 hours before the dye is ready to use. I recommend mixing the dye the night before you plan on using it, so that you can dye your hair first thing in the morning.

You can leave the dye on your hair anywhere from 1 to 4 hours, so it’s a good idea to do this on a weekend, when your schedule is flexible.

Here’s what you’ll need to prepare a batch henna hair dye:

  • Glass or wooden bowl (avoid using metal)
  • Wooden spoon
  • 1 packet of 100% natural henna hair dye
  • 2 cups brewed black tea, cooled
  • 1-3 tablespoons apple cider vinegar
  • 1-3 teaspoons ground cinnamon (for a pleasant smell)
  • Oil, for protecting your scalp
  • Shower cap
  • Gloves, to protect your hands
  • A towel to protect your shoulders and neck
  • Hair clips, for sectioning your hair

Directions:

  1. Pour the packet of henna powder into a large bowl and add in the apple cider vinegar and cinnamon. The more vinegar you add, the deeper the end results will be.
  2. Slowly add the black tea to the red henna and stir until it’s the consistency of yogurt. The mixture should not drip from the spoon, but should be easily spreadable. (You might not need to use all 2 cups of tea.)
  3. Cover the bowl with plastic wrap (I used a shower cap), pressing on the plastic to remove any excess air, and let it sit for 8-12 hours. If you used all 3 tablespoons of vinegar, it’s a good idea to let it sit for the full 12 hours. You’ll know the dye is ready to use when it turns to a darker brown-red color from its original green color.
  4. To apply the dye, section your hair with 3-4 hair clips and cover your shoulders with a towel. Apply oil to your hairline and ears to protect them from staining, then use gloved hands to apply the henna to dry hair.
  5. Wrap the dyed hair in a shower cap to keep the henna moist and warm, then leave the mixture in your hair for 1-4 hours. Do not leave it in overnight.
  6. Unwrap your hair and rinse with water. Do not shampoo your hair until 24 hours after the henna process for best results. The full color will appear after 72 hours, and the color will last 8-12 weeks.

You’ll want to repeat this process again 72 hours later, to allow the red color to fully develop, so that you can cover the red with your desired color, such as brown or black.

I recommend choosing one shade lighter than you think you want, so that in case you don’t like the resulting color, you’ll still have the option of going darker. (Remember, it’s hard to lighten your hair after using henna!)

I used the Medium Brown color (which is a mix of henna and indigo) after applying the red henna color, and I’m really impressed by how well the brown color neutralized the red hue. If you’re looking for a good non-red henna hair dye, I think this color worked well!

And here’s a look at the full “before and after” transformation, from the lighter, highlighted hair to the medium brown shade:

Tips for Using Henna Hair Dye:

  • Be sure to follow the directions above, remembering to have gloves and a towel ready to protect your skin before the dying process. (Ask me how I know.) This process gets messy fast, so you might even want to dye your hair in a dry shower so you can simply rinse it down after you’re done.
  • Don’t add too much liquid to the hair dye. The first time I dyed my hair, the red henna stuck to my hair well under the shower cap, but the second time I added too much liquid and the dye was dripping down my forehead through the shower cap for over an hour. I would have let the dye sit on my head longer, but I couldn’t take the dripping any longer! So, add less liquid than you think you should, just to be on the safe side.
  • When I used the red henna hair dye, I didn’t realize that the dye was supposed to sit covered for 8-12 hours, so I ended up using it after only 4 hours of rest, and I think the color still turned out well. I’m not sure how different it would have looked had I let it sit longer, but I was happy with the result regardless! (And in the photos above, I only let the red color sit on my hair for 1 hour before rinsing.)

I hope sharing this process will help you naturally cover up any gray hairs, if that’s your goal, or to have fun trying a new hair color without using chemical dyes.

  1. I have for years dyed my hair with henna,I started using red teas with it, like it much better than black tea! Good article!

  2. Hi- I was wondering if you are still using henna or if there is a semi-permanent brand of hair dye you recommend? I have been using henna but it’s so unpredictable. I really want to use a semi permanent hair dye and get highlights but am afraid of the chemicals and hair loss.

  3. I have white and black but more white and I want a little bit of black Hannah is when I want to go which color should I use the medium brown dark brown

  4. Thank you for this post! I have a few questions and am wondering if anyone can help?

    1) If I’m using henna for the first time and have grey roots, should I use the henna all over my whole head this first time (and not just the roots) so that the henna color will be uniform throughout my hair?

    2) Do you have to wait 72 hours between the red and brown applications? I saw another video where the stylist did the red color, let that process for an hour, and then applied the henna with indigo/brown.

    3) I like the look of some depth and dimension in hair color, rather than having hair that looks like one “block of color,” which is totally unnatural. Is there a way to achieve this? For example, maybe there’s a way for my greys to keep a lighter color as opposed to the rest of my non-grey hair?

  5. For the two-step process in covering gray hair, I was wondering if in the first process instead of using pure henna, to mix maybe henna with cassia to lessen the dark red in the first step? And then the second step would be indigo and Henna? Do you need to just use henna by itself for the first step? Or can the first step be effective by using a mix like I stated?

  6. As this post reveals the comments are years old do not know if I will get a reply but am feeling hopeful!.
    I went to the Morocco Method website and am wondering if I should buy two packets of brown, two red and wondering about the amla powder ( if you have tried it) to get the results I am looking for, to have enough products in one order to tide me over for a month or more.
    Lastly, how often do you repeat the process or did you find it too much trouble to keep up months, or now, years later?

  7. How long after I apply the red henna do I have to wait to apply another color (to color completely gray hair)?

  8. I’ve tried a few times to dye my hair with henna. My hair’s black, so I did the red dye first, then indigo second. Followed instructions to the tee to make sure the henna was activated. As much as I really wanted this method to work, it didn’t provide the coverage I wanted or last as long.
    After dying my hair with the indigo, it would fade within a week.

    Is there something special you have to do to get this to work on very dark hair?
