Uh, no. Your hair and nails do not grow after you die. It'a a 100-percent myth promoted by horror movies. Almost. Because there is a bit of truth to it.
Your hair and nails stop growing pretty much as soon as you die. Both nails and hair grow from the base up when new cells develop and push old ones out. And the growth of new cells requires things like oxygen and sugar things that are no longer available after someone dies.
But and this is a creepy but when someone dies, their skin dries out and pulls away from nails and hair. So, although they dont actually get longer from base to tip, hair and nails appear to grow after you die.
