A nail is a horn-like envelope covering the tips of the fingers and toes in humans, most non-human primates, and a few other mammals. Nails are similar to claws in other animals. Fingernails and toenails are made of a tough protective protein called keratin. This protein is also found in the hooves and horns of different animals.

Fingernails grow from the matrix. The average growth rate for nails is 0.1 mm each day or 1 centimetre in 100 days. The exact rate of nail growth depends on numerous factors including the age and sex of the individual and the time of year. Fingernails grow faster than toenails. The fingernails on the right hand of a right-handed person grow faster than those on their left hand, and vice versa. The little fingernail grows slower than other fingernails. The great toenail grows faster than other toenails. Fingernails lose elasticity as they begin to lose water. As a result, the nails will be harder and may crack.

Currently, there is an increasing awareness of hand and fingernail healthcare as healthier fingernails can promote healthier lifestyles. To improve the strength and appearance of fingernails, people can consume gelatin, which will help build thicker, stronger nails. Gelatin can also contribute to hair health, as well, although it will not significantly impact the rate of growth for human hair. Dietary imbalances can cause spotting or ridges on the nails, and an overload of certain toxins can also have an impact on nail growth and appearance.

Each nail consists of several parts, including: Lunula, Free edge, Nail Root , Nail Bed, Perionychium, Hyponychium and Cuticle,

A healthy finger nail has the function of protecting the distal phalanx, the fingertip, and the surrounding soft tissues from injuries. It also serves to enhance precise delicate movements of the distal digits through counter-pressure exerted on the pulp of the finger. The nail then acts as a counterforce when the end of the finger touches an object, thereby enhancing the sensitivity of the fingertip, even though there are no nerve endings in the nail itself. Finally, the nail functions as a tool, enabling for example an extended precision grip pulling out a splinter in one’s finger, and certain cutting & scraping actions, opening closed cans or fingernail storage.



Fingernail storage is a method of writing data onto a human fingernail using a pulsed laser. The fluorescence of the nail, when exposed to ultraviolet ight, is increased at points where data is written. Data can be read from the fingernail using a microscope while irradiating the nail with UV energy. Fingernail storage has been suggested as a biometric means of identification, and also for storing critical medical information for use in emergencies. It can also be used as an unintrusive means for automatically recognizing the identity of individuals for instance keystroke dynamics. The patterns of rhythm and timing created when a person types. The roots of keystroke dynamics go back to the early days of the telegraph, when individuals developed distinctive patterns that identified them. This pattern was known as the fist of the sender
