Can the black henna paste or crust stain my clothes?
Yes. They can stain your clothing and the stain will not come out. So until you have washed the black henna paste/crust off, keep it away from your clothing and any other objects. Once you have thoroughly washed the paste/crust off of your skin, the actual black henna tattoo on your skin will not stain clothing. It is only the crust and the paste that can stain clothes, carpeting, leather, etc. So be very careful until you have washed the excess off.
