Nail wraps are formed by cutting pieces of fiberglass, linen, silk fabric, or another material to fit on the surface of the nail (or a tip attached prior), to be sealed onto the nail plate with a layer of resin or glue. They do not damage the nail and also provide strength to the nail but are not used to lengthen it. It can also be used to fix broken nails. The treatment is however more expensive.

( May 2012) ( Learn how and when to remove this template message) A healthy fingernail 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. [2]

With only a few exceptions, primates retain plesiomorphic (original, "primitive") hands with five digits, each equipped with either a nail or a claw. For example, nearly all living strepsirrhine primates have nails on all digits except the second toe which is equipped with a grooming claw. Tarsiers have a grooming claw on second and third toes. Less commonly known, a grooming claw is also found on the second pedal digit of owl monkeys ( Aotus), titis ( Callicebus), and possibly other New World monkeys. [37] The needle-clawed bushbaby ( Euoticus) has keeled nails (the thumb and the first and the second toes have claws) featuring a central ridge that ends in a needle-like tip. This suggests that whereas claws are useful on large-diameter branches, wide fingertips with nails and epidermal ridges were required for habitual locomotion on small-diameter branches. It also indicates keel-shaped nails of Callitrichines (a family of New World monkeys) is a derived postural adaptation rather than retained ancestral condition. [38] See also [ edit ] The conditionas also called as nail atrophy, results in atrophy or wasting away of the plate thus making it lose its sheen. The body of nail gets smaller and in some cases, falls off completely. Onychatrophia can affect adults (men and women), infants and children, and toe as well as fingernails. Onychatrophia is not likely to cause discomfort or pain. This often occurs after an ailment or injury. A nail-biting encounter with the woman who has the longest fingernails".

Finally, the nail functions as a tool enabling a so-called "extended precision grip" (e.g., pulling out a splinter in one's finger), and certain cutting or scraping actions.

PMID 22042603. S2CID 3939930. Manicures (for the hands) and pedicures (for the feet) are health and cosmetic procedures to groom, trim, and paint the nails and manage calluses. They require various tools such as cuticle scissors, nail scissors, nail clippers, and nail files. Artificial nails can also be fixed onto real nails for cosmetic purposes.

This can affect the adhesion of any artificial products, such as regular nail varnish, UV gels or powder polymer or liquid monomer. It also weakens the nail and opens it up to penetration by unwanted substances. The lower and younger layers are attached firmly to the nail bed epithelium which, in turn is attached to the nail bed by a series of grooves. The nail is an unguis, meaning a keratin structure at the end of a digit. Other examples of ungues include the claw, hoof, and talon. The nails of primates and the hooves of running mammals evolved from the claws of earlier animals. [36]
