Henna tattoos are created from a paste derived from the leaves of the henna plant. It is applied to the skin for decorative and symbolic purposes. Henna is worn for important ceremonies, like weddings, and is believed to bring the wearer prosperity for their marriage. There are several designs to choose from, including traditional mehndi patterns, which are deeply symbolic and can also represent good health and happiness. It takes several hours before the henna is absorbed into the skin and several weeks before it fades. It is, in general, considered safe to use, although black henna can cause serious health risks. You should also be aware that wearing henna designs when they are not part of a traditional practice can be considered disrespectful and a form of cultural appropriation.
