Henna Hair Dye in Rich Copper, Warm Brown and Glossy Black

Rich copper that glows in the sunshine, soft chestnut brown, or deep, glossy black: choose your shade and mix it at home with our henna hair dye. Each powder is a plant-based hair dye, triple-sifted and 100% pure, with no PPD, ammonia or peroxide, just plant leaf that colours and conditions at the same time. Start with our Henna Powder (Mehendi) for warm copper and auburn, then layer our Indigo Powder over it for brown through to black. Love your shade and just want shine? Our Neutral Henna (Cassia) is a cassia powder that adds body and gloss and leaves your colour exactly as it is.

Natural hair colour develops differently on each person, especially on grey, lightened or previously coloured hair. The final shade depends on your starting colour, preparation, and application method. Before using henna hair dye, follow the product’s safety instructions and do a strand test to judge the result.

Which Henna Hair Dye Gives the Shade You Want?

Why You'll Love Our Henna Hair Dye

  • Your shade, your way. Copper, auburn, chestnut, brown or black: with our henna hair dye you choose the powders and set the timing, so your natural hair colour turns out exactly as rich as you like.
  • Just pure plant leaf. Every plant-based hair dye here has nothing added: no added colours, fragrance or preservatives, and it is free from PPD, ammonia and peroxide. Our pure henna is Lawsonia inermis leaf grown in Rajasthan.
  • Triple-sifted for a silky paste. We finely mill and triple-sift our henna powder and indigo, so the paste glides from root to tip and rinses out cleanly.
  • Colour that conditions. A henna hair dye wraps each strand in colour while conditioning, leaving hair glossy, soft, and fuller-looking. It also helps reduce breakage, a well-known henna benefit for hair.
  • Rooted in Ayurvedic tradition. Henna has been part of Indian hair care and mehendi celebrations for generations. Every powder is PETA-certified, vegan, and cruelty-free, from a UK family business with over 40 years of Ayurvedic care.

How to Apply Henna Hair Dye at Home

StepWhat to do
1. Patch and strand test48 hours before you use any henna hair dye, dab a little paste behind your ear or on your inner elbow, and colour a small snip of hair to preview the shade. Repeat the patch test each time you colour.
2. MixStir your henna powder into warm water until it's as thick as yoghurt, then leave it to rest for a few hours so the colour releases. Mix indigo fresh, just before use.
3. ApplyWear gloves, section clean, dry hair and work the paste from roots to ends. Henna stains, so wrap an old towel round your shoulders.
4. WaitCover with a shower cap and keep warm. Henna hair dye: 1 to 3 hours. Indigo, over-rinsed henna: 45 to 90 minutes.
5. RinseRinse with water until it runs clear and wait a day or two before shampooing. Your natural hair colour will settle and deepen over the next 48 hours.
How oftenRefresh your henna hair dye at the roots every 4 to 6 weeks. Cassia makes a lovely glossing mask in between.

Five Shade Recipes to Try

New to henna hair dye? Start with pure henna on its own. It's the easiest to mix, gives a beautiful warm copper on almost every shade, and shows you how your hair takes plant colour. Then try these:

  • The copper glow. Mix henna powder with warm water and a lemon squeeze, then leave on for about 1 hour. A bright, sunny henna hair dye that warms up any shade.
  • The rich auburn. Pure henna rested for a few hours, then left on for 2 to 3 hours. Deeper, wine-tinged warmth that glows beautifully in daylight.
  • The soft chestnut. Henna hair dye for 1 hour, rinse, then indigo powder for 45 minutes. A gentle, natural-looking brown from a fully plant-based hair dye.
  • The glossy black. Henna hair dye for 2 hours; rinse, then indigo powder for 90 minutes. Repeat after a week or two for the deepest, richest tone.
  • The shine-only gloss. Mix cassia powder with warm water and a spoonful of Amla, then leave on for 30 to 45 minutes. Glossy, bouncy hair, keeping your colour as it is.

Choose your henna hair dye above and enjoy colour you've mixed yourself, from bright copper to glossy black. To keep hair soft between colours, try our natural hair powders, a nourishing hair mask for dry hair or our Ayurvedic hair oils, and find every herb in our full natural powders range.

FAQ

What are the henna benefits for hair?

Beyond colour, henna coats each strand, so hair feels thicker, looks glossier, and is easier to manage. It helps reduce breakage and leaves a soft, healthy-looking shine that many people love as much as the shade itself. Because our henna hair dye builds with each use, your natural hair colour grows richer and warmer every time.

How do I use indigo powder for hair to get brown or black?

Indigo works as the second step. Colour with henna first, rinse and dry, then apply freshly mixed indigo powder for 45 to 90 minutes. Shorter gives a soft brown, longer gives a deep black, and 2 or 3 sessions build the richest tone. One of the best indigo powder benefits is that it conditions as it colours, leaving hair smooth and glossy.

Does henna hair dye cover grey hair?

Yes, beautifully. Henna hair dye turns greys a warm copper, and the two-step henna-and-indigo method takes them to brown or black. Our natural hair dye for grey hair page walks you through covering greys step by step.

How much henna powder do I need?

Our 100g pack of henna hair dye suits short hair or a roots touch-up. For shoulder-length hair, our Henna Powder 200g is a good fit, and for long or thick hair, or if you colour regularly, our Henna Powder 500g gives you plenty for several sessions. Keep any spare powder sealed in a cool, dry cupboard.

Can I use pure henna over hair I've coloured before?

Yes, many people do. The final shade depends on the colour already in your hair, so a strand test is a useful way to preview it. Colour a small snip from underneath, let it settle for 48 hours, and you'll see exactly how your plant-based hair dye looks before you colour your whole head.

Is cassia powder the same as henna hair dye?

They're close cousins with different jobs. Henna gives copper colour, while Cassia, often called neutral henna, conditions and adds body, fullness and shine without colouring dark hair. Our cassia powder is a favourite weekly mask between colours, and it suits fair hair beautifully too, with a strand test first.

How long does natural henna hair colour last?

A plant-based hair dye like henna stays in the hair and softens gently over time, so it doesn't change sharply as it grows. Most people refresh their roots every 4 to 6 weeks, and each application adds a little more depth. Indigo tones soften slightly faster, so a quick indigo top-up keeps browns and blacks rich.
