Can you color a dead person's hair?

Yes. Human hair is dead anyways, so coloring it alive or dead doesn't make a bit of difference. If your hair was alive it would hurt to get a haircut =) your hair is mostly made of keratin (protein), thus making it grow....and Hair and nails continue to grow for a short period of time after death so, the deceased might need that touch up color.
