Water and Dye Release in Henna and Indigo
Generally, throughout the British Isles water and dye release in henna and indigo are not considered a problem and the water seems to work beautifully for both henna and indigo herbal hair colour. But if you’re in the UK, or outside the UK, and not getting good dye release from your henna and indigo, we suggest you buy distilled bottled water to mix up your henna powder and a high ph / mineral rich alkaline water to mix up your indigo powder, such as bottled mineral water. Just make sure from the information on the label that it really is a mineral rich water and not just labelled “spring water” or “mineral water” as some waters are which don’t originate from anywhere remotely near a spring and don’t contain traces of any minerals. For cassia obovata, the water type shouldn’t make any difference at all.

Watch out for Water and Dye Release in Henna and Indigo in Scandinavia ! ( an Indigo trouble spot)
We advise those living in Scandinavia to use distilled bottled water or tap water to mix your henna, and to buy bottled mineral water (e.g. Evian) to mix your indigo. Alternatively, for indigo, combine bottled mineral water with aloe vera juice which will also helps prevent any irritation from indigo. Do persevere – if you’ve previously tried henna and indigo and it didn’t work, please change the water and try again.
This is why water works for indigo in some countries and not in others :
The water in most Scandinavian countries, and some European countries, is not chemically treated in the same way as water in other parts of the world such as the UK and USA, with the result that countries like the UK and USA have alkaline rich water. This is because the UK and USA add chemicals such as Fluorine and Chlorine to water to kill bacteria.The UK and USA say the addition of these chemicals is necessary because of pollutants in acid rain, and they advocate health benefits. In Scandinavian countries you generally have purer, more acid, water. But, because it may be not as chemically / alkaline charged as our water, that means, unfortunately, it doesn’t kick start indigo.
