The nail plate is the most visible part of your nail. The nail bed, on the other hand, is the fleshy area located beneath the nail plate. It supports the hard part of the nail as it grows and provides nutrients and protection to the nail plate. The nail bed can be damaged by trauma, disease, or infection, which may cause changes in colour or texture. If the nail bed is severely damaged, it may be necessary to remove the nail plate. The regeneration of the nail bed depends on the extent of the damage. In some cases, doctors may use artificial nail beds to help the nails grow back. Typically, fingernails grow about 2.5mm a month and toenails grow at half the rate of fingernails. It can take up to 3 to 6 months for a completely new nail to grow.

What You'll Learn
Nail bed regeneration
The nail bed is the fleshy area located beneath the nail plate. It is composed of tightly packed cells called keratinocytes, which are constantly shed and replaced. The nail bed provides nutrients and support for the nail plate and helps to protect the sensitive tissue beneath. Nails grow out of the nail matrix, which is the moon-shaped whitish area at the base of the nail. This means that nail beds regenerate from the nail matrix.
Injuries to the nail bed can result in damage to the nail plate, causing it to become misshapen or discolored. If the nail bed is severely damaged, it may be necessary to remove the nail plate. The nail bed can also be affected by disease or infection, which may cause changes in color or texture. Whether or not a nail bed can grow back after being damaged depends on the extent of the damage. If only the top layer of the nail bed is damaged, it is likely that it will grow back on its own. However, if the damage is severe, it may not grow back.
In some cases, doctors may use artificial nail beds to help the nails grow back. It is important to take care of your nails to prevent injuries. Nails are made of keratin, a tough protein that can still be injured if hit or knocked hard. To prevent injury, it is recommended to wear gloves when doing activities that could damage your nails, such as gardening or housework. It is also important to be careful when using sharp objects, such as knives and scissors, and to trim your nails regularly and file them down.
Additionally, there are ways to make your nail beds appear longer. This includes avoiding certain habits such as cutting your nails too short or biting your nails. Pushing back your cuticles and allowing your nails to grow longer can also help elongate your nail beds.

Nail growth tips
Yes, the nail plate will grow back. The nail bed regenerates in the presence of the nail matrix, so the nail plate will grow back as new nail plate cells form and multiply underneath the skin.
Now, here are some tips for growing your nails:
Keep your nails painted and avoid water: One user says that keeping nail polish on their nails has made the biggest difference in terms of nail growth. They do three layers of polish and two of the top coat and get a week and a half out of their polish. They also recommend avoiding water as the nail plate absorbs it, expands, and becomes brittle over time.
Use a strengthening base coat and cuticle oil: One user says they are using a strengthening base coat and Hard as Nails twice a day. Another user recommends cuticle oil one to two times a day and hand cream after each hand wash. Cuticle oil helps to hydrate the nail bed and cuticle, and dry nails will break and chip while well-moisturized nails will grow long. You can also use nourishing oils like coconut oil, olive oil, or argan oil if you don't have cuticle oil.
Take supplements or eat a well-balanced diet: One user recommends taking biotin, but another warns that it can cause breakouts for some people. Instead, you can eat a well-balanced diet to ensure the proper intake of vitamins including zinc, biotin, folate, and protein to maintain nail growth.
Gently groom your nails regularly: Dr. Viscusi says that frequent nail clipping can help stimulate circulation in the nail bed and help nails grow. Keeping nails smooth and filed also reduces the risk of breakage.

Nail plate function
The nail plate is the most visible part of the nail, and it has several functions. It is a protective plate that covers the tip of the digits (fingers and toes) of primates, corresponding to claws in other animals. The nail plate is made of a tough, rigid, translucent keratin protein that protects against infection. The pinkish appearance of the nail comes from the blood vessels underneath it. The underside of the nail plate has grooves that help anchor it to the nail bed, and the ridges on the ventral nail plate surface increase the surface area of attachment to the nail bed. The nail plate is attached to the nail bed, which supports the hard part of the nail as it grows.
The nail bed is the skin beneath the nail plate, and it includes the hyponychium and the onychodermal. These layers of tissue prevent pathogens from infecting the skin underneath the nail plate. The nail bed is highly innervated, and the removal of the nail plate is often painful as a result. The nail bed does not produce a stratum corneum, but if the nail plate is lost, the nail bed loses its longitudinal ridges and begins to express the keratins necessary to produce the stratum corneum.
The nail matrix is the active tissue that generates new nail plate cells. It includes the lunula, the whitish crescent-shaped base of the nail that is most visible on the thumb. The lunula appears white due to the reflection of light where the nail matrix and nail bed meet. The width and thickness of the nail plate are determined by the size, length, and thickness of the matrix. The matrix will continue to produce cells as long as it remains healthy and receives nutrition. As new nail plate cells are made, they push older cells forward, and the older cells become compressed, flat, and translucent. This makes the capillaries in the nail bed visible, resulting in a pink colour.
The hyponychium is the area of epithelium underlying the free edge of the nail plate, sometimes called the "quick". It provides a waterproof barrier and protects the distal phalanx, fingertip, and surrounding soft tissues from injuries. The nail acts as a tool, enabling an "extended precision grip" and certain cutting or scraping actions. It also enhances precise delicate movements of the distal digits through counter-pressure exerted on the pulp of the finger.

Nail injuries
Nails are composed of protein and fat and are not made of live tissue. The most visible part of the nail is called the nail plate, which sits on top of the nail bed. The nail bed supports the nail plate as it grows and protects the sensitive tissue beneath it. The nail matrix, the moon-shaped whitish area at the base of the nail, produces new nail plate cells.
If the nail is completely detached from the finger or toe, it cannot be reattached. If there is damage to the nail matrix, the nail will grow back with a defect. Minor damage will produce minor defects, while more significant damage can result in a permanently deformed nail. If there is any damage to adjacent tissues, the nail bed, the nail matrix, or the proximal nail fold, it should be assessed by a physician and repaired if appropriate.
To prevent nail injuries, it is recommended to wear gloves during activities that could damage nails, such as gardening or housework. It is also important to be careful when using sharp objects and to trim and file nails regularly.

Nail infections
The nail plate is the most visible part of your nail. The nail bed supports the nail plate as it grows. The nail bed includes the hyponychium and the onychodermal, which are layers of tissue that prevent pathogens from infecting the skin underneath the nail plate.
Symptoms of paronychia include pain, swelling and tenderness around the nail, skin that is red and warm to the touch, and pus that builds up under the skin. A white to yellow, pus-filled abscess may form. If left untreated, the nail can start to grow abnormally and may have ridges or waves. It may look yellow or green, and it can be dry and brittle.
Most nail infections get better with antibiotics. Healthcare providers may also drain the pus and culture the fluid to determine the specific bacteria causing the infection. In some cases, the infection lasts a long time or comes back after treatment.
Fungal nail infections are also common. The nail becomes thick, discoloured, and easy to break. Toenails are more commonly affected, but it can happen to fingernails as well. The infection usually starts at the edge of the nail and slowly spreads to the rest of the nail. It can be treated with antifungal nail medicine or antifungal tablets.
