Henna

       The tattoo that parents love, non permanent! Henna is made from henna leaves and is sold as a powder (made by drying, milling, and sifting the leaves) which is in turn mixed with lemon juice, strong tea, or other mildly acidic liquids. With the right mixture it will turn out almost like toothpaste (it will keep the shape) making it easy to do all of the detailed designs.
         Henna dyes (or stains the skin) because of the "lawsone" molecules in the leaves. When the paste touches our skin the lawsone binds to the proteins in our skin cells, hence staining them.
          Once the paste is made, it needs to sit for 6-12 hours to make sure all the lawsone is released from the leaves. Then once applied, a good stain can be achieved in just minutes, but it can be left on for up to a couple of hours to make the stain as dark as possible. Also before hand you can put on a oil with high levels of "monoterpene" alcohols to help improve the stain; for example tea tree, eucalyptus, cajeput, or lavender
