The Dangers of Paraphenylene Diamene / PPD Hair Dyes
The truth is that there is no such thing as “black henna” or “colour henna”. There is only one henna plant and its scientific or botanical name is lawsonia inermis. It produces an orange red colour and nothing else, unless it’s mixed with something else – the crucial question is whether that “something else” is natural or chemical. “Chemical”, in my view, spells danger and even death. PPD is chemical.

Look for Pure Hair Dye, not Chemical Hair Dye
Once you understand what PPD is and learn to recognise the common chemicals in hair dye, you’re armed with information to help you make an informed choice. Watch out because even some packets of “henna” have “paraphenylene diamene” listed as an ingredient in tiny print on the leaflet inside the box. Research also reveals that many brands sold as “natural henna” which don’t contain paraphenylene diamene DO contain green dyes which are not listed as additives and which made the powder look artificially fresh lime green in colour, thus rendering the henna impure and adulterated. Real henna is not bright green or any shade of lime green ; it’s more a dull khaki, kind of “mud”green.
