“We buy the Desert Shadow Henna/Indigo organic hair dye. The instructions are clear, it works well and Wholesome Hub arranges delivery promptly. We tend to mix the henna the night before (it needs longer) and the indigo in the morning. I apply it for my wife, so even a man can do it! It seems to have helped my wife's hair, which was thinning due to using store-bought hair dyes. There is a good range of colours. Being East Asian she uses the Chestnut Shadow colour. We recommend Desert Shadow.”
“This produces a good dark brown and good grey coverage. Reading indicates that might make sense to prepare the part 1 (henna) at a alight warmer temperature to release more of the active ingredient: lawsone. But obviously one then needs to be cautious.”
