Final answer:
A layer of any kind of nail enhancement product is used to reinforce the natural nail, which consists of the nail matrix, nail plate, and nail bed, important for nail growth and protection.
Step-by-step explanation:
A layer of any kind of nail enhancement product that is applied over the natural nail is designed to strengthen and beautify the nail structure. The natural nail itself is comprised of the nail matrix, which is a deep layer of epidermal tissue at the proximal end of a nail where nail growth occurs. This matrix produces the nail plate, or the visible part of the nail, as cells multiply and push outward. The nail bed is rich in blood vessels, giving it a pink appearance, and the cuticle, or eponychium, is a layer of dead epithelial cells protecting the nail from infection.
