How long does hair last after death?

Answer 1

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.

Answer 2

until you chop that hair off ;) though it'll fade after you dye it and keep fading until a certain point

it depends on how fast your hair grows really hope that helps

Answer 3
