This is a technical function, not an actual function. The body doesn't produce more hair and nail tissue, but both of these things do 'grow,' in the days after death. What actually happens is the skin loses moisture (although cosmetics companies are probably hard at work making a cream for that) and pulls back, exposing more hair and making nails seem longer. Since you do measure the length of hair and nails from the point where they meet the skin to the tip of the hair, the hair does 'grow'.
I have more you want more???
If you were a homicide detective investigating a stabbing death, how could you determine if the victim was alive at the moment of the stabbing?
ask the onlookers at the Scene
