I used it, but I did not like it at all. I had previously used Surya Henna. I applied it and left it in my hair overnight. When I rinsed it out, my hair felt soft and it had a nice shine. 2 months later, I used Rainbow. With the Rainbow Henna, which I only left in for about 1 1/2 hours as it specified because I used a color. (The Surya Henna was not a color, I was using it for the conditioning benefits) The Rainbow Henna seemed to change the texture of my hair, and not for the better. Thank goodness I have a close cut, so by the time I get my next hair cut, it will all be out. I would not recommend this Henna. Stick with the PURE hennas. I will be going back to my Surya Henna. Lesson learned: If you find something that works for ya, stick to it!
