Understanding what these ridges mean is important for maintaining both nail health and overall well-being. While some ridges are harmless and simply a part of the aging process, others can be indicative of nutritional deficiencies or more serious health conditions.

Fingernails are composed of a protein called keratin, which is also found in hair and skin. The nail plate, which is the hard part of the nail, is made up of layers of dead keratin cells. Beneath the nail plate is the nail bed, which is rich in blood vessels and provides nutrients to the nail.

The growth of fingernails occurs from the nail matrix, located under the cuticle. On average, fingernails grow about 3 millimeters per month, although this can vary based on factors such as age, diet, and overall health. The structure of the nail is designed to protect the sensitive tips of our fingers and enhance our ability to grasp and manipulate objects.
