What is dye used in mehndi decoration?

Dye is not commonly used in traditional mehndi decoration. Mehndi, also known as henna, is made from the leaves of the henna plant. When the leaves are dried and crushed, they release a natural dye called lawsone, which stains the skin. This is the same dye used in traditional mehndi designs.

However, some modern mehndi artists may use black henna, which is a synthetic dye that is not derived from the henna plant. Black henna contains a chemical called para-phenylenediamine (PPD), which can cause severe allergic reactions and should be avoided.

It is important to ensure that the mehndi being used is made from natural henna and does not contain harmful chemicals.
