I had heard about using henna on hair a while back, but I was put off by all the work you have to do to use it. One day, I copped out and bought a package, mixed it with lemon juice and hot water, and let it sit overnight. The next day, I added some rosemary and paprika (for smell and color enhancement, respectively) and I put the goop in my hair. In spite of the rosemary, it still smelled a bit too much like hay for my initial liking. And it makes your hair feel yucky. You also have to leave it in for at least a few hours with a plastic cap to keep it clean and warm. Anyway, after rinsing out, I have to say that all the trouble was completely worth it. My hair was a gorgeous shade of deep red. It was glossy and fuller. Apparently, henna binds to the hair shaft making each hair thicker. It even took away my dandruff problems. So I use henna once every month or two, and it is now dark and thick and growing fast. I haven't had a haircut in over 6 months, but I still don't have many split ends to speak of.
