Black tea? As a hair dye?

I know. I thought it sounded weird too. But then, we do use green tea as a hair rinse, and I even use herbal teas in bath recipes, so this really shouldnโ€™t have come as a surprise!

I was surprised with the results when my husband told me he was going to try this recipe on his graying hair (haha!) 

He spritzed some on after showering, left it in for a few minutes, then rinsed and dried his hair with a towel – typical man style. 

And an hour or so later, his hair looked totally different. Darker, with less grey! 

Now, I personally donโ€™t mind his graying hair, but he hates it, so the fact that such a simple recipe can hide grey hairs made him immensely pleased. 

In this post, Iโ€™ll share the secret recipe for how to darken gray hair naturally – by just using black tea and water in a spray bottle. 

It works great! And it is super easy to make. Do note, black tea only works on naturally dark hair and has not been tested on dyed hair.

If youโ€™re feeling at all self-conscious about graying hair or simply want to get rid of those greying wisps, then this black tea for grey hair is the product for you!

Black tea for grey hair

It turns out that black tea to dye hair is not that new on the beauty scene.

I mean, it was new to us when we tried it! But worldwide, black tea hair dye has been used for centuries

Itโ€™s a traditional method used to dye grey hair in countries such as China and India, made famous because itโ€™s a natural and non-toxic dyeing method, heralding back to ancient times. 

The darkening effect of black tea on hair isnโ€™t permanent, however. It will likely last a couple of washes, but thatโ€™s it. You can always add more, though, when you want to. 

The dyeing effect of black tea comes from the natural tannins contained in tea leaves.

So too, the caffeine in tea is a great contributor to hair health. It acts as a stimulant for the hair, and some even believe it helps hair grow stronger and faster.

How to darken gray hair naturally

You will need the following:

Instructions:

Bring the water to the boil.

Remove the pot from the heat, add the tea bags, and steep for at least an hour.

(I let it steep with the lid until it cooled completely, but you can remove the lid after an hour to speed up the process.)

Once cooled, transfer to a spray bottle (for easy application) and store in the fridge until ready to use.

How to use black tea to darken grey hairs

The best way weโ€™ve used this recipe to cover gray hairs is to apply it using the spray bottle mid-showering. 

So, start by shampooing your hair as you would normally. 

Then, before adding conditioner, you spray the black tea on generously and leave it in while you wash your body in the shower.

After those few minutes, simply rinse and condition your hair and then dry it naturally or with a blow dryer.

Black tea benefits for hair

  • Darkens gray hair naturally – the tea tannins carry out the dyeing process without damaging the hair, which is great news, as gray hair is naturally fragile and prone to breakage. 
  • Natural and non-toxic – using black tea spray is considered safe for hair. 
  • Adds shine and condition – did you know? Black tea tannins help revive the hair, adding strength and vitality to your beautiful locks. 
  • May stimulate hair growth – the caffeine content of black tea is believed to prompt the hair to grow quicker and more robustly, especially if you apply it to the scalp region. 
  • Delivers antioxidants – tea is naturally full of antioxidants that fight harmful free radicals, reducing โ€˜wear and tearโ€™ on the hair strands.

FAQs/Tips

  • Use a towel to dry your hair that you wonโ€™t mind spoiling. Black tea is notorious for stains and marks on clothing and can ruin home items if youโ€™re not careful!
  • This black tea spray works great for darkening a few wisps of grey hair, but it wonโ€™t cover a whole head of gray – neither is it suitable for blonde or lighter hair. Only try using this if you have naturally dark hair. 
  • You can leave this black tea spray in for up to an hour at a time. The longer you leave it on, the stronger the result. 
  • This is a low-cost and easy way to darken gray hairs. No need for expensive hair dyes!
  • This black tea spray lasts up to 2 weeks stored in the fridge. 
  • The dye effect is temporary… black tea spray is certainly not permanent and will need โ€˜topping upโ€™ every few days if you wish to hide gray hairs for longer. 

I hope you enjoyed reading this post. Itโ€™s definitely one of my husbandโ€™s favorite gray hair home remedies!

    Will the color run when I sweat?

    1. Laura says:

      It shouldn’t as it acts as a dye.

  2. Ellie says:

    Have you tried adding black tea to a shampoo or conditioner? Is there a way to incorporate it into a product that people already use to reduce the hassle? Thanks!

    1. Laura says:

      Hm, thats an interesting idea, that I haven’t thought of!

  3. Laura says:

    hmm. Is red/brownish hair considered dark?

    1. Laura says:

      You can try it!

    2. Jasmine says:

      Iโ€™ve read that if youโ€™re blonde you can use chamomile tea and for redheads, use rooibos.

  4. Maree says:

    I normally love your home remedies, unfortunately this one didn’t work for me. I made a really strong brew and left it on for at least 5 minutes. No noticeable improvement – I was really hoping it would work. I’m wondering if it would work better on dry hair??

    1. Laura says:

      I have not tried it with dry hair. If you still have the tea leftover, you could try leaving it in for up to an hour before lightly rinsing it out. Though I would probably wear a shower cap!

  5. Denise Messner says:

    Riid sounds like a great idea going to try it thank you for the great tios

  6. Sarah Magezi says:

    I will try it out,I have grey which I don’t like and I hate dyes as they make my hair so hard

    1. Laura says:

      This is a much better and safer option!

  7. Bassel says:

    hello, I always like your recipes, however I tried this one on my dad but it didn’t work ๐Ÿ™

    1. Laura says:

      You can try making a stronger tea but using less water and an extra tea bag!
