Hey there. I have been using henna on my hair for around 8 years. After having every hairdo and color you can think of, with every product made before making some serious lifestyle improvements, I can say I LOVE henna for haircolor. It always looks natural (kinda bright at first few days, though, depending on color), and conditions without all the chemical crap. I have recommended and assisted several friends, and they are all converted, even the ones that have used the same chemicals products for years. If your hair is not white-blond, you have a big selection of henna colors to choose from. Personally I prefer the reds. Unless your hair is pretty dark or ash-toned already, if you want natural-looking results, don't use Black. Henna is really easy to use,too...and MUCH cheaper than other products (I have long hair and get 3-5 applications from a box, around $6.00) I prefer a brand called "Light Mountain". Easily available at whole foods stores and color batches are fairly consistent. Henna washes out gradually, but without roots! My friend with pretty much grey hair applies henna every month or so, I do it every two to three months. A word: I have heard hennaed hair alters the way later commercial dyes perform, so if you plan to return to another product, you may want to look into this before trying henna. Have fun!
