Henna (Lawsonia inermis) is a spiny shrub from the Lythraceae family that grows in oasis and desert regions. In Morocco, its cultivation primarily thrives in the eastern desert, along the Tafilalt -Draa Valley and Tata axis. It is used in traditional medicine as well as a beauty product for hair dyeing, hair care, and the embellishment of hands and feet. The henna ceremony is a part of Moroccan tradition and remains unchanged on certain festive occasions such as circumcision, engagement, wedding, religious festivals, etc. It is also used as a sign of great joy when receiving guests who have been absent.
