The same great henna mehendi already prepared in cones for direct use.
Pure herbal product from nature. Ground Indigo leaves. These are often used in the Indian subcontinent for applying to hair. Dark black in color when applied, it leaves a burgundy color on washing.
Hena is also extensively used in Indian tradition during weddings. There are dedicated mehandi nights before weddings where all the women get together to apply henna tattoos to each other's hands and feet making beautiful and artistic designs. These kind of tattoos are especially good as firstly they are temporary (lasting about 1 week) and second because they are made on top of the skin using henna paste just in a plastic, hence no needles are required.
