The nail matrix is the most important structure within the nail unit. This is where new nail plate cells are created and as these new cells are created, older cells are pushed forward and the nail plate grows. The shape and size of the matrix determines the thickness and width of the nail. The longer the matrix, the thicker the nail, and vice versa. Damage to the matrix can cause a range of different nail imperfections, such as white spots or ridges, and weaken the nail plate as a whole.

Does nail matrix grow back?
