Layering Indigo on top of long term Henna?

[Zemeraldite]

Does anyone know how hard it is to layer indigo on top of henna treatments?

I had ombred hair which I hennaed for a year and getting bored of it. Thinking to switch back to black (natural hair colour) but I don't know how easy it is... Will it take a lot of repeated layering, or will henna still somehow peak through? Should I do a 2 step method, or mix henna and indigo together?

Any advice would be so so helpful!

Thanks

If you put indigo on there, mix a tad bit henna (about 2-5%) in it, so the consistency is smoother. Other than that, it should be just fine. If you are already henna'd you only need the second step.

Having lots of henna underneath is actually a good thing For black I recommend the two step method.
