How to use henna

Henna is the natural alternative to synthetic hair dye. It's easy to get glossy, rich hair colour at home, and we show you how to get the shade you want.

Our bricks are made using the finest-quality Persian henna, conditioning cocoa butter and gorgeous essential oils that leave your hair looking and smelling fabulous. Choose from four shades:

Rouge is a vibrant red that glints gloriously in the sunlight, with deep tones brought out by a pinch of coffee and shininess helped by fresh organic lemon juice. 

Brun contains indigo and a pinch of ground coffee to tint your hair a deep chocolate brown colour, with nettle powder to tone and soothe the scalp. 

Marron turns hair a shiny chestnut colour with autumnal tones thanks to a splash of lemon juice as well as a pinch of ground coffee that adds depth.

Noir is the one to use for a rich-blue black shade, as we've used lots of indigo herb here. We've also used a little red henna to add extra shine without bringing out any red tones.


You will need:

• Rubber gloves

• A bain-marie or a heat-proof bowl in a saucepan

• A spoon for stirring

• Newspapers on the floor

• Clips to section your hair

• Dark-coloured towels

• Cling film/shower cap

• Ultrabalm/Ultrabland to cover your hairline and ears

• Colouring brush to apply henna (or use gloved hands)


1. Firstly, do a strand test to check you’re happy with the colour (especially important if you’ve got chemically-treated hair) - the shade will continue to develop for up to 24 hours after you apply it. Just add boiling water to a small amount of henna in a heat-proof bowl and then use rubber gloves to apply to a strand of hair about half an inch wide. Leave for an hour or two, and then shampoo, rinse, dry, and leave for 24 hours.

2.To apply to the whole head if you’re happy with the strand test, chop up the henna brick into small pieces and drop into a bain-marie. Cover the pieces with boiling water, which melts the cocoa butter and releases the ingredients. Stir until the henna is the consistency of melted chocolate, adding more hot water if needed – the hotter the henna, the better the results.

3. Smooth Ultrabalm or Ultrabland around your ears and hairline to prevent stained skin. Wearing rubber gloves, apply the henna to clean, dry hair and work through section by section, back to front. Start with the roots and smooth through the length of your hair. Let it sit for one to three hours (for a redder shade, wrap hair in cling film or a shower cap) and then shampoo, rinse and dry. The colour will develop over 24 hours; apply as many times as you like to build a rich colour and shine.


Which shade is for me?

Rouge is the full-on red henna, turning blondes and greys into fiery redheads. Those with naturally dark brown hair will see a more subtle result; a warm natural red tone with a glossy sheen which will catch in the sun.

Marron will give blondes shiny hair the colour of autumn conkers. Brunettes will get a pleasing reddish tinge, though less pronounced than those using Rouge.

Brun will make blonde hair several shades darker, giving a rich coffee-coloured glaze. For brunettes, this is the shade to use if you want the conditioning benefits of henna without drastically changing your natural colour.

Noir is mixed with indigo to give a black gloss with a very slight reddish tinge. All hair will go several shades darker after using this shade.

Always do a strand test first. Everyone’s hair is different, so you can’t be sure how yours will react to henna.

Hey I am using hair dye for the first time and I went for Caca Brun as my hair is brunette and I didn't want to do anything too extreme for my first go. Problem is, I melted all of the henna block but did not use it all because my hair is quite short. What do I do with the rest of the paste? I really don't want to throw it away becuase it was quite expensive and I want to reapply in a week or so. I was thinking of freezing it. Would freezing the leftover paste be okay? What have other people done if they have remaining dye?? Thanks :))

Hi Guys! Just a super quick question: I'm about to dye my hair with henna for the first time, and I was wondering about what happens when you're washing it out. Will the dye stain my shower cubicle? And will it ruin my bedsheets when I go to sleep after dying it? Just don't want to end up with more of a mess than there already will be!

I have auburn hair that is on the more brownish side plus a lot of grey hairs. It also is thick and about shoulder length and can be curl/frizzy if I don't tame it. I used the Caca Marron and fell in love with how much more red I was able to get with it. When the sun would catch my hair I would be a fiery red head. To use the henna I used the whole block and just stuck it in a big boil and poured boiling water over it. I scrapped at it and slowly broke away chunks until it was similar to brownie batter. This seemed to work fine and I had to issues with it. Also when washing out the henna I found the best way is using a lot of conditioner and just going over my hair a bunch of times to get it all out. I believe it lasted in my hair for about 2-3 months. 5 months later I had about an inch of root showing. The smell is terrible but I found as long as I did not wash my hair or get it wet it was more manageable, also keeping it up for the first few weeks helped with the smell. I hope that was helpful for anyone with similar hair

Does anyone know how long caca rouge will stay in middle / dark blonde hair? I have never used any products to dye my hair before. My hair is also a little wavy. At the Lush store, they told me it would last 1-2 month, because I use it for the first time and because of my wavy hair. thanks! :)

I have an idea which is to make the fibres of the henna brick soften more so may be then it will be easier to apply as well as absorb into the hair better. I pour hot water to the broken pieces and let them soak overnight but will this make the lush henna lose effect?

Hello everyone! I wanted to replay to girls who failed to cover greys. It happened to me, I bought maroon lush henna and it didnt cover my greys and the new grown 4cm part of hair and already coloured part was maroon. I went to Lush store in Westfield and they told me to first colour my whole hair with red one because that is the basic henna and it covers it all and u even the colours of your hair. Than after that you use the colour you want. So here I am, bought both brown and red preparing my self for 5 hours of being covered with henna hahaha and a bottle of red. :-) I will write you how it went.

Hi, I have lots of grey and really want this to disappear! Did it work when you dyed it red first?

Hi - I'd love to know how it went...hope it was okay? x I have naturally dark brown hair and its starting to really 'go' grey at the temples. I had such severe allergic reactions to expensive boxed up dyeing kits that I'm now terrified of dyeing it and I had it cut to just shoulder length - hoping to 'get away with' gracefully going grey - however, I'm looking gradually more 'washed out' with this greying temples effect (my eyebrows and lashes are still really dark brown - which makes the greying head hair look worse). I would LOVE to brighten myself up! My hair dresser keeps trying to temp me to having a skin test to use their (expensive) bottled dyes which I will NEVER do :( so I'm very happy to have found a natural alternative in Lush Henna! However, would welcome advice on dying the greying temples and what colour to use just for this - as a 'trial' for later whole-head use.....
