It depends. If it is permanent hair dye, then it last until you either recolour it or cut it. Assuming it is a darker color, then it will fade some over time and of course your new hair growth will come in your natural color. If it is temporary color, then it will last a few weeks depending on the color of dye and the color of your hair.
