Nails are made from keratin, the same protein that makes up our skin and hair. They protect the soft tissue beneath them and prevent injury. Nails grow back after being removed or falling off, but it may take a while. The rate of regrowth depends on several factors, including age, climate, hand dominance, and overall health. In adults, it can take anywhere from six months to two years for a fingernail to grow back and up to 18 months for a toenail.

What You'll Learn
Nails grow back, but slowly
Losing a fingernail or toenail can be a distressing experience, but it is reassuring to know that nails do grow back. The nail matrix, the "factory" where your body makes new nails, ensures that your nails regenerate. However, this process takes time, and it is important to understand that nail growth occurs at a slow pace.
On average, it takes about six months for a fingernail to grow back completely, and this timeline can vary from person to person. Toenails typically take even longer to regrow, with a timeline of up to 18 months. Several factors influence the speed of nail regrowth. For instance, nails tend to grow slower in older adults and in colder climates. In contrast, nail growth is often faster during the summer and in the dominant hand.
Trauma or injury to the nail can increase the rate of regrowth due to increased blood flow to the affected area. However, it is crucial to note that severe nail trauma or matrix damage may result in partial or complete nail loss, requiring medical attention. In such cases, proper medical care and treatment can promote healthy nail regrowth.
While waiting for your nails to grow back, it is essential to keep the nail bed clean, dry, and protected. You can apply petroleum jelly and cover it with an adhesive bandage until the nail bed is firm or the nail has grown back. Additionally, watch for signs of infection, such as increasing heat, redness, pain, tenderness, swelling, or pus.
Overall, while nails have a good regeneration capacity, the process is gradual. With proper care and patience, you can expect your nails to grow back, though it may take several months or even a year for them to fully regenerate.

Fingernails and toenails grow at different rates
Fingernails and toenails do grow back in adults, and they grow at different rates. On average, fingernails grow about twice as fast as toenails. This is because the cells in the body that produce nails, called matrix cells, are more active in the fingers than in the toes.
The growth rate of fingernails and toenails can vary depending on various factors such as age, health, and genetics. For example, nail growth tends to slow down as people age, and certain medical conditions or nutritional deficiencies can also affect nail growth.
In general, fingernails take about 4 to 6 months to regrow completely, while toenails can take up to twice as long. The specific growth rate will vary from person to person, and even between different nails on the same hand or foot. For instance, the middle fingernail typically grows the fastest, whereas the thumb nail tends to grow the slowest.
The difference in growth rates between fingernails and toenails lies in the different functions and needs of these digits. Our fingers are used for more precise and intricate tasks and thus require more sensitive and flexible nails. On the other hand, our toes bear more weight and require stronger and more durable nails.
Nail health is an essential aspect of overall personal hygiene and well-being. Proper nail care includes keeping them clean, trimmed, and free from infection. Maintaining a healthy diet and lifestyle to support strong nail growth is also important. This includes consuming adequate amounts of nutrients such as biotin, vitamin A, and protein.

Nail matrix damage can affect nail growth
Fingernails and toenails have good regeneration capacity, but they grow slowly. It takes about six months or longer for a fingernail to grow back and up to 18 months for a toenail. Nails are intended to provide protection to fingers and toes, as well as aid in opening, scratching, and tearing. Just like other body parts, they are susceptible to injury and disease.
The nail matrix is the "factory" where new nail plate cells are created, and as these new cells are formed, older cells are pushed forward and the nail plate grows. The nail matrix is responsible for nail growth, thickness, width, and shape. The size and shape of the matrix determine the characteristics of the nail. The longer the nail matrix, the thicker the nail, and vice versa. A larger and wider matrix corresponds to a thicker nail, while a smaller matrix leads to a comparatively thinner nail.
The nail matrix is vulnerable to damage and disease. Trauma to the nail can cause the production of new nail cells to stop for as long as three weeks. Nail growth will usually resume at a faster rate and steady after about 100 days. You may notice the nail appears thicker than usual. The extent of the injury often depends on where it occurs. If you have a deep cut or trauma to the germinal matrix at the base of the nail, it's possible the nail may never grow back.
Injuries and certain health conditions can damage your nail matrix and interfere with nail growth. Minor matrix damage can temporarily change your nail's appearance. You might notice a change in how your nail feels to the touch. A severe injury could cause your nail to fall off. Once your nail matrix heals, your nail will usually start to grow again. In cases of severe nail matrix damage, some or all of your nail may not grow back.

Nails protect the skin underneath
Nails are protective plates that cover the tips of our fingers and toes. They are made of a tough, rigid protein called alpha-keratin, which is also found in claws, hooves, and horns of vertebrates. The nail plate is made up of tightly packed, hard, keratinized epidermal cells that grow out from the nail bed. The nail bed is a specialised form of skin epithelium with the same four layers as the epidermis of the skin. The nail plate is analogous to the stratum corneum layer of the skin.
The nail matrix, located under the base of the nail, is the "factory" where new nail cells are produced. About 90% of nail growth comes from the germinal matrix, while the remaining 10% comes from the sterile matrix, which is more important for keeping the nail attached to the underlying skin. The nail matrix is made of special cells that continuously produce new cells, which harden as they move outward from the nail root to the nail plate, causing the nail to lengthen and strengthen over time.
The cuticle, a small strip of skin at the bottom of the nail, acts as extra protection from germs entering the nail bed. The eponychium, or perionychium, is the fold of skin cells that produces the cuticle. Together, the eponychium and cuticle form a protective seal. The hyponychium, or "quick," is the thickened portion of epithelium underlying the free edge of the nail plate, forming a seal that protects the nail bed.
In addition to protecting the sensitive skin underneath, nails also serve other important functions. They help enhance precise delicate movements of the fingers through counter-pressure exerted on the pulp of the finger. Nails act as a counter-force when the fingertip touches an object, thereby increasing the sensitivity of the fingertip.

Nail bed injuries are common
There are several types of nail bed injuries, and they can occur together. Some heal with home care, while others require medical attention. A subungual haematoma, for instance, is a bruise that forms when small blood vessels under the nail bed leak, and blood pools between the nail and the nail bed. This usually occurs when the fingertips or toes are crushed or subjected to heavy impact. A nail bed laceration is when the nail and underlying nail bed are cut, usually by a sharp object. This will likely bleed, and you will be able to see the cut through your nail. As it heals, a large bruise may appear.
A nail bed avulsion is when the nail and part of the nail bed are pulled away from the rest of the finger, either partly or entirely. This commonly occurs when the finger gets stuck or jammed in something. Avulsions can be extremely painful and cause the finger to swell. Finger fractures are also common with this type of injury, and the nail will likely have to be removed.
The most common complication of nail bed injuries is a hook nail, which occurs when the nail doesn't have enough bony support and curves around the finger. This can be treated by removing the nail and trimming some of the nail matrix. In the case of a split nail, the nail is removed, the scar is treated or removed, and a new nail is allowed to grow.
