I bought Henna from an Indian store that imports 100% henna. I mixed the Henna with lemon juice and a powder that makes mustard yellow (www.hennaforhair.com) for a brown effect. The results, a slight change in my hair color, the greys (the few I have)were turned a reddish brown. I probably will not do again, too much time, the results are slight and the smell stays for days. If your hair is dark, you'll have the same results.
