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.
Leave the henna on as long as possible! The longer you leave the henna on, the darker the color will be and the longer it will last. Leave it on a minimum of 1 hour; overnight is best. 3. Take extra steps for a better stain.
