Yes, but you won't get a very long lasting tattoo. Some people only get a day or two. Most won't even get a week. For some reason, the skin on the neck does not take the black henna well. Also the chest area, on some idividuals, doesn't last as long as other parts of the body (maybe a week or a week and a half).
