First of all, it is really easy to use, so that isn't the problem. I used it for my eyebrows and I needed to use the color black because even the black one isn't dark and deep enough (I have tried dark brown as well, I bought them bot). I do prefer to go to the beauty salon to do it with Henna because that's deeper and darker. But I'm in another country now so i decided to try it myself. I know this is not especially for eyebrows but for the people who were wondering if it's possible for the eyebrows, it is, but it's really subtle. By the way, I used a new toothbrush to get it on my eyebrows and if you want to try it to I would advise this black one (I bought dark brown as well) and leave it on for about 3 hours or 4. Don't wash it off after 1.5 hours, that's what I did the first time and then you don't see anything at all. My advise for eyebrows, go to a beauty salon or use powder, I wouldn't advise (this) henna.
