Light Mountain Color the Gray! Black 7 oz Box

This is my first time using this brand where the henna and indigo were separate treatments. I tried a different brand that had henna and indigo mixed together previously and it didn't cover the gray but it could be that I didn't use enough. Henna is messy no matter how you apply it. I had to use 2 packages because I have very long hair down to my lower back. I also added the amla from Swanson's. I don't have a lot of gray, but the black henna did change change the gray to a reddish color. I left it on longer than what the directions stated and used coffee instead of water. I then used the indigo color the next day and it turned the red strands black. Again, very messy and I used 2 boxes. It definitely covered all the grays. I really can't find any gray hairs now. My hair is already black but this did darken it more, which I like. I'm not sure if it's normal but each time that I've used henna treatment, which is a total of 3 times in my lifetime, regardless of the brand, the color comes off on my hands, skin, clothes, pillow cases, etc. It's been almost 2 weeks and the color is still coming off.
