Nail growth is the process by which the nail matrix, located at the base of the nail, produces new nail cells. These new cells push the older cells forward, causing the nail to grow. The average growth rate of fingernails is about 3 millimeters per month, while toenails grow at a rate of about 1 millimeter per month.
There are a number of factors that can affect nail growth, including genetics, age, diet, and overall health. For example, people with thyroid problems or certain vitamin deficiencies may experience slower nail growth. Additionally, certain medications, such as chemotherapy drugs, can also slow down nail growth.
