Henna Mehendi is a natural, plant-based powder created by drying and crushing the leaves of the henna plant. When mixed with water or other liquids, it forms a paste that can be applied to the skin or hair. Henna paste has the unique property of staining the skin or hair with a reddish-brown or coppery color. It is often used to create temporary body art designs, such as henna tattoos, and to dye or color hair in various shades of red or brown.
