Hi there
I know black henna is said to be harmful, but whenever someone returns from holiday, they have had it put on form, Dubai, Morocco, so there must be a safe version too? By black I mean, once you do the design onthe hands it remains like a very dark black, does anyone know of any online shop this can be purchased from?
Thanks
I was meant to put this post under Lifestyle, beauty, I don't know how to move it ?? ............
Re: Black henna
I’m a professional Henna Artist and I know for sure there is no such thing as Black henna …Henna is only green in colour when it is in powder form and stains maroonish red..but I’m sure you know that already.
The black stuff these people use is PPD Para-phenylenediamine..It can scar you for the rest of your life…It is seriously dangerous..This PPD is used to make stuff to clean the carpets..now we can’t drink that can we..similarly we can’t apply that on our skin..Mehndi only stains the outer layer of our skin..where ppd goes through the skin and into our blood and can give us serious scars…check this link.
If you are looking for something similar to black henna but safe…then there is some thing called Jagua its extract of a fruit from south America. you can apply that ..it will give you a blackish blue stain. which will stay fro about a week or so. another thing is Harqus.
there are couple of websites those sell safe jagua and harqus..let me know if you want to get some. 
take care
