Henna is a plant-based dye derived from the leaves of the Lawsonia inermis plant. It has been traditionally used for various purposes, including body art, hair dyeing, and natural cosmetics. In many cultures, henna is particularly popular for creating intricate temporary designs on the skin, often during special occasions and celebrations such as weddings or religious festivals. It is known for its reddish-brown color and is applied to the skin in paste form, which leaves a stain after drying.
