I've been slacking. I keep forgetting to brew the coffee before hand. Also I miss henna, but I don't trust the ones at my local Indian store anymore since I saw ppd in the ingredients list. Gonna shop around online and see.
For those that hendigo with pre-mixed henna and indigo (like the rainbow brand) do you notice it not lasting as long as buying them separately? I'm not planning on doing a two step process for jet black, just a medium brown colour. How is grey coverage?
