White henna is a type of temporary tattoo ink that is made from a mixture of water and a thickening agent, such as cornstarch or white glue. It is used to create designs that are similar to traditional henna tattoos but are white or silver in color.

White henna is often used to create more subtle or delicate designs and is popular at music festivals, parties, and other events. It is also sometimes used as an alternative to traditional henna tattoos for people with sensitive skin or allergies to the chemicals found in henna.

However, it is important to note that white henna is not the same as pure henna, which is a natural dye made from the leaves of the henna plant. White henna does not contain any of the natural dye compounds found in henna and therefore does not have the same coloring properties. It is also not as long-lasting as traditional henna tattoos, and will typically fade within a few days or weeks.

If you are considering getting a white henna tattoo, it is important to make sure that the ink does not contain any harmful additives or chemicals. It is also a good idea to do a patch test first to see if you have any reactions to the ink. To do a patch test, apply a small amount of the ink to a patch of skin and wait a few days to see if any reactions occur.
