Oh my gosh. i used these products based on the instructions and my hair is jet black. for years i tried to find a natural way to dye my gray hair without chemicals and this did the job. No more chemical dyes.
I've been bleaching my hair since I was a teenager. I got tired of this as my hair was just not what it used to be plus I needed to tone it all the time because it was yellow and not blonde. In my first batch I ordered cassia and henna which ended too orangey on my bleached hair. Next batch was cassia, henna and indigo. Next time I'm going to use henna and indigo (50:50).i think that will be the winning combination. I'm quite pleased as it is with 1/3 of cassia, 1/3 henna, 1/3 indigo. But I want o get it a bit darker so will do the third combo this weekend probably.
Using the 2 step process to cover white hair which I have had since a teenager - I was really desperate to move away from box dyes especially re dark colours. I added lemon and coffee to the henna when prepping it and salt to the indigo. It is very effective and works out to be cost efficient too. The dyes are VERY powerful so I didn't need the whole packet of either. Also - mega bonus - they did not stain the bathtub! Other henna/indigo products have and were really hard to clean up. Basically - I am really pleased with the quality and the very helpful instructions included. I will certainly return for future purchases.
I use this product for more than 2 years and I am perfectly happy. Not only it 100% covers grey hair, but it also makes them shine and look healthier. The combination 2 indigo/1 henna matches my natural dark hair color
Really recommend this product. I have naturally really dark hair and this covers the greys (or whites in my case!) I find I get the best result when I first use the henna alone and then dye with the indigo powder.
