Nails

A manicure is a cosmetic beauty treatment for the fingernails and hands enjoyed by both sexes. A manicure can treat just the hands, just the nails, or both.

Contrary to common belief, the structure of the nails is not related to the structure of bone, and taking extra calcium will not strengthen brittle nails. Neither will taking gelatin.

Fingernails—and toenails, too—are products of your epidermis and are composed of the protein keratin. Each nail grows outward from a nail root that extends back into a groove of skin.
