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.
Remember that the property in henna that dyes the hair red, is the same one that conditions, strengthens, defrizzes, and smoothes. So even though youâre using less henna, it will still leave a slight red tint on dark hair (similar to drawing on black paper with an orange crayon), and dye your grays red.
