How long does Henna Hair Dye last? Henna Hair Color is a semi-permanent dye and gradually wears off over a period of approximately 8 to 12 weeks. This time period usually coincides with new hair growth, meaning that your roots will match your henna hair color for a nice, even coat most of the time.
Henna is applied to clean, dry skin. This can take anywhere from a few minutes for a simple design to 4 or 5+ hours for a heavy bridal mehndi. Once dry, it will be sealed with a sugar solution, or taped with medical tape (for body pieces). Let henna paste set for 8 hours, though overnight is traditional and guarantees the best color.
