do nails and hair grow after death?
Nails and hair may appear to keep growing, but this is because flesh shrinks as it dries out, retracting the skin to make the nails and hair appear longer. There is a little truth in the story though, because death isnât an instantaneous process. When someoneâs heart stops beating their brain cells die very quickly, but cells that use less oxygen can live a little longer. So potentially hair and nails could grow a tiny bit after the brain is dead.
