1. Nails are made of a protein called keratin, the same material found in hair and animal hooves. 2. The average growth rate for nails is about 3 millimeters per month, although this can vary depending on age, health, and other factors. 3. The white half-moon shape at the base of the nail is called the lunula and is actually the visible part of the nail matrix, where new nail cells are produced. 4. Fingernails grow faster than toenails, and nails on the dominant hand grow faster than those on the non-dominant hand. 5. Nails can reveal a lot about a person's health, with changes in color, texture, or shape sometimes indicating underlying conditions such as anemia, thyroid disorders, or fungal infections.
