Do a personâs hair and fingernails continue to grow after death? Hair and fingernails may appear longer after death, but not because they are still growing. Instead, a persons fingernails and hair may appear longer because the skin around them has retracted, according to the Dermatology Clinic at UAMS. After death, dehydration causes the skin and other soft tissues to shrink.
Skin cells, meanwhile, are longer lived. Grafts can still be successful if taken 12 hours after death. In order for fingernails to grow, new cells need to be produced and this canât happen without glucose. Fingernails grow by an average of 0.1mm per day, a rate which slows as we age.
