Hi everyone. Hope you are all well.
Baddison, I am not familiar with that brand of henna, and I have never used it or heard of anyone using it. As with any blends of henna and herbs you can try the product out but there are a few factors to consider:
It might not stain as well, because usually indigo does not have the same dye release timing as henna does. Doing them seperately and blending them together gives best results.
It might not be as fresh.
The sift might not be as great and might not wash out well. Jamila is the best henna powder for washing out. Specifically, Jamila 2008. All of those crops are best for washing out, and then their henna for hair by Jamila.
I hope this helps. My last suggestion would be to do a hair strand test if you are going to try it out. Once you use 100% pure herbs though, you might not go back to anything else.
