The nail bed is the part of the deep surface of the nail that supports the nail and has the function of protecting the nail, and the rich capillaries in the nail bed can provide nutrients for the nail. The nail matrix, on the other hand, is a specialized hair-bearing epithelial structure that is the starting point for nail growth. If the nail bed and the nail matrix are not damaged, the child’s nail cover is lifted, is able to grow normally.
Since the nail bed is the substance that provides nourishment to the nails, if the nail bed is damaged, then the nails will not be able to obtain nourishment, and the nail matrix belongs to the starting point of nail growth. If there is damage to the nail bed and the nail matrix, a child with a lifted fingernail cap will usually not grow back.
