Fingernails are the hard coverings that protect the tips of our fingers. They are composed of a tough protein called keratin and grow from the nail matrix, located beneath the cuticle. Fingernails can vary in shape, size, and thickness among individuals. They serve multiple purposes, including aiding in tasks like grasping objects, protecting the fingertips, and providing support to the delicate tissues of the fingertips. Fingernails can be cared for by keeping them clean, trimming them regularly, and moisturizing the surrounding skin. They can also be adorned with nail polish, nail art, or artificial enhancements for aesthetic purposes. Proper nail care promotes healthy growth and helps maintain the overall well-being of the nails.
