How Does a Toenail Grow

The way a toenail grows is out of the matrix, which is the little pocket under the skin. It constantly is creating new cells, which lengthens the nails by forcing the old ones to get pushed together and grow out. When the cells finally grow out of the matrix, they are dead.

Where does your toenail grow from?

Toenails grow from the matrix. The nails are composed largely of keratin, a hardened protein (that is also in skin and hair). As new cells grow in the matrix, the older cells are pushed out, compacted and take on the familiar flattened, hardened form of the toenail.

How is a toenail formed?

When cells at the root of the nail grow, the new nail cells push out the old nail cells. These old cells flatten and harden, thanks to keratin, a protein made by these cells. The newly formed nail then slides along the nail bed, the flat surface under your nails.
