Henna, also known as mehndi, is a plant-based dye that has a rich history dating back to ancient times. Its ingredients include henna powder, lemon juice, and essential oils, which are mixed to create a paste that is applied to the skin, where it dries and leaves a temporary design. Henna is integral to traditional celebrations in South Asia and the Middle East, symbolizing good luck and prosperity for the bride and groom. Henna's popularity has spread beyond its traditional regions of use, with the growth of social media platforms such as TikTok. However, it is important to note that not all henna products are safe, and some contain toxic ingredients. Henna also has medicinal properties and has been used to treat various ailments for centuries.
