Colouring Grey Hair Black

HomeHelp Centre

To get a strong dark colour on grey hair there is no 100% natural hair dye which is very easy and quick to apply. Our natural henna based powder hair dyes are the strongest products for getting a strong colour on grey hair.

It is not possible to get a black shade on grey with one application, it has to be a 2 step process. The best thing to try for the most effective way to get black on grey hair is pure henna and indigo. We have many customers who manage to get a black shade with this. But it doesn’t work for everyone.

Henna and Indigo 2 Step Process

This is a technique of using pure henna (with no other plants added) and pure indigo (with no other plants added) applied in separate applications. In a nutshell, you mix up pure henna paste and leave it on your hair for a couple of hours, rinse it off and dry your hair, and your grey hair goes orange. Then you apply pure indigo paste and leave that on for a couple of hours and then rinse that off and the orange hair turns black.
So it's not a short process, but it's worth it. This henna followed by indigo technique achieves a true black, and is entirely natural. Pure Henna and Indigo can be purchased here.

Dark Brown Followed by Indigo

If you don’t want to use a layer of red henna on your hair you could try first dying your hair with the It’s Pure Organics Herbal Hair Colour Dark Brown. On white/grey hair this may not be as dark as dark brown but if all your grey hair is covered to at least a light to medium brown shade you can then apply another application of pure indigo paste and leave this on your hair for a couple of hours. Indigo paste should not be applied to very light coloured or grey hair as it can go a bluish colour. It's Pure Dark Brown can be purchased here.

Everyone's hair is different in terms of your initial colour, and the structure and chemistry of your hair. So it reacts differently to different colours. This makes it impossible to predict exactly how the colour will be on different people’s hair.
For this reason, we always recommend strand testing before putting it all over your hair. See this article about how to strand test. If you have a lot of grey at the temples the grey tends to be resistant and it may not give a very strong coverage there.

Tester Sizes for the 2 Step 'Hendigo' Process

If you want to try some of these before dying your whole head, we sell testers of all of them, so you could do some strand tests. Here are the links to see the tester sizes:

Customers Pictures of Using a 2 Step 'Hendigo' Process:

This customer applied henna to colour her grey red, washed it out, dried her hair and then applied indigo to colour the red black. It has to be a 2 step process because Indigo cannot be applied directly to grey hair or it goes a strange blue/green colour.

Please Note Chemically Lightened Hair May React Differently. If your hair has been chemically lightened with peroxide this is another factor in the equation and will affect the colour results. Chemical lightening does damage your hair and it can make it more porous and make it behave differently. Sometimes the chemically lightened hair behaves the same as if it was your natural hair colour. However, sometimes it absorbs too much colour in which case the colour will be stronger than expected.
