There are so many brands selling Indigo powder these days that its really confusing while deciding which one to buy. All of them claim to be natural and organic and yet prices are so different. I bought it after trying a few others. Found the product to be satisfactory. I use it as a hair colour in addition to henna. only henna makes the hair orange and red, so i mix indigo in the henna paste. This makes the hair dark brown (not black). However, if you use it separately AFTER applying the henna, then the hair looks black or really dark brown.
