Nail matrix

The nail matrix is the growth zone of the nail. It lies under the rear nail fold, i.e. under the skin at the base of the nail. Its front, visible part is the lunula. New cells are constantly formed here; they keratinise and are pushed forward as the nail plate.

Why is it so important?

If the matrix is injured – e.g. by a knock, pressure or inflammation – the nail may grow back permanently deformed, thickened or split. That is why we work particularly carefully around the base of the nail.

Good to know

Toenails grow much more slowly than fingernails: about 1 to 1.5 mm per month. A complete big toenail needs 12 to 18 months to grow back fully – which is why treating nail fungus takes so long.
