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.
I recommend that you leave the mehndi on your skin for as long as possible - i.e. 4-6 hours, to achieve the darkest color, but remember that good henna will produce a reasonably brown stain after an hour. In any case, after at least 2 hours, scrape the mehndi off of your skin with a blunt knife or with your fingernails.
