Scintillating ScienceIt’s a common myth that your hair and nails continue to grow after death. While this is not true, it certainly looks that way and that’s part of what frightens people. In fact, what happens is that, with no blood flow, your skin begins losing moisture after death. This lack of moisture causes your skin to shrink and pull back, which in turn reveals more of your hair (straight down to the follicle), while also exposing more of your nails. In other words, your hair and nails aren’t growing, they are simply exposed.
