Can the indigo powder that is used to dye hair be used to dye clothing as well? I am in Europe and it will be hard for me to get the pure cake described in many of the posts on here, as I wuold have to order it which would be expensive. I have seen a lot of indigo dye for fabric on sale in stores but am tad wary of it.
Hi catherine i wanted to know if it was ok to dye my hair black with zarqa black henna which claims to have ground indigo leaves only. I mixed it in water and it doeesn't seem to have any additional harmful black dyes, but is just green indigo powder, that is claimed to be safe to use on hair?
