Before diving into the techniques of shaping nails, it's important to understand the anatomy of nails. Nails are made of a protein called keratin, which is also found in hair and skin. Each nail consists of several parts: - Nail Plate: The visible part of the nail.- Nail Bed: The skin beneath the nail plate.- Cuticle: The tissue that overlaps the nail plate and protects the nail matrix.- Nail Matrix: The tissue under the base of the nail that produces new nail cells.
