Fingernails And Hair Stop Growing After Death
Once the blood stops circulating after death, that’s the end of it. A few hours after a person dies, the corpse’s skin dries out, which means the skin retracts at the fingertips.
This creates a visual effect that makes it seem like their nails are longer. Since men’s facial skin also gets dehydrated, their 5 o’clock beard appears to look like it has grown longer. But if there is no blood circulating, there won’t be any cells to produce hair and fingernail tissue.
