Henna tattooing, also known as Mehndi, is an ancient art that originated in Egypt over 5,000 years ago. It involves using a paste made from the henna plant to create temporary designs on the skin. Henna grows in tropical regions and was traditionally used in ceremonies and life events in places like Egypt, the Middle East, and India. Over time, henna tattooing has become popular in Western cultures as well, though the designs are often simpler. Proper application of henna paste involves grinding the leaves, mixing with oil, refrigerating, then squeezing the paste through a stencil or freehand onto the skin where it dries and leaves a design.
