The rate at which human nails depend on the person and which nail you are looking at. Finger nails grow 5 times faster than toe nails and the longer the finger is, the faster the nail grows on that finger. Another factor of the growth rate of nails is the age of the person. The younger the person is, the faster the nails grow. In order to grow strong and better looking nails, people should consume gelatin, which will make the nails thicker.
