The nail matrix is the tissue located under the base of the nail, just beneath the cuticle. It is responsible for producing new nail cells, which harden and form the visible part of the nail. The health and function of the nail matrix are crucial for nail growth and overall nail appearance. When the nail matrix is damaged, it can lead to various nail problems, such as irregular growth or deformities. Factors like injury, infection, or certain medical conditions can affect the nail matrix. Proper care and protection of the nails can help maintain a healthy nail matrix and promote optimal nail growth.
