Which part of the nail is most susceptible to injury and infection?

The matrix is the part of the nail that is most susceptible to injury and infection because it is responsible for nail growth. Located beneath the cuticle, the matrix is where new nail cells are formed. If the matrix is injured or infected, it can lead to issues like nail deformities, discoloration, or even permanent damage to the nail growth process. Infections in the matrix can occur due to trauma, such as hitting the nail, or due to bacterial or fungal infections entering through breaks in the skin around the nail. Given its crucial role in nail formation and its location beneath the protective layers, the matrix is particularly vulnerable to harm.
