The growth of a nail bed can be observed through the length of the white tip of the nail. Nails grow at a rate of 0.13 inches or 2.5 millimetres per month and can take 3 to 6 months to completely regrow. The growth of a nail bed can be affected by factors such as genetics, diet, overall health, and certain injuries or illnesses. Damage to the nail bed can cause whitish discolouration, dents, and separation of the nail plate from the nail bed. To promote the growth of the nail bed, it is important to maintain healthy habits such as avoiding nail biting, trimming nails regularly, and protecting nails from trauma.
| Characteristics | Values |
|---|---|
| Nail growth rate | 2.5 mm per month or 0.13 inches per month |
| Nail growth time | 3-6 months for fingernails; 12-18 months for toenails |
| Factors affecting growth rate | Genetics, dominant hand, season (faster in summer), overall health, diet, trauma, and habits (e.g., nail biting, cutting nails too short) |

Nail growth rate
The growth rate of nails is typically about 2.5 millimetres or 0.1 inches per month. It can take anywhere from 3 to 6 months to grow a completely new nail. Toenails grow more slowly than fingernails, usually at about half the rate of fingernails. Fingernails can take 6 to 9 months to grow back completely, while toenails can take 12 to 18 months. Nails on the dominant hand and during the summertime tend to grow faster.
The nail matrix is the part of the nail that produces new nail plate cells and is often referred to as the "factory" where new nails are made. It includes the lunula, the white, moon-shaped area at the base of the nail. The nail bed is the area under the nail plate, which is the hard part of the nail that is visible. The nail bed includes the hyponychium and the onychodermal, which are layers of tissue that protect the skin underneath the nail plate from pathogens.
Injuries and certain health conditions can damage the nail matrix and affect nail growth. A severe injury may cause the nail to fall off, but with proper medical care, it will usually grow back. In cases of severe damage to the nail matrix, the nail may not grow back at all or may grow back deformed. Certain illnesses, such as severe eczema or psoriasis, can also interfere with nail growth and cause changes to the appearance of the nail.
To promote healthy nail growth, it is important to take good care of your body and maintain a well-rounded diet and good general health. Avoiding certain habits, such as biting your nails or cutting them too short, can also help nails grow longer. Treating any underlying infections or conditions that may be affecting nail growth is crucial. In the case of nail separation or onycholysis, antifungal medications or discontinuing the use of certain nail products may be recommended.

Nail bed trauma
The nail bed is the area under the nail plate, which is the hard, visible part of the nail. The nail matrix, located under the base of the nail, is responsible for producing new nail plate cells. When the nail bed is damaged, it can affect the growth of the nail, causing ridges, bumps, or deformities. However, with proper treatment, healthy nail growth can often be restored.
There are several types of nail bed injuries:
- Subungual hematoma: This occurs when small blood vessels under the nail bed leak, causing blood to pool between the nail and the nail bed. It is usually the result of a crush injury or heavy impact and can cause throbbing pain and discolouration of the nail.
- Laceration: A laceration is a cut that pierces the nail and the nail bed beneath. It is typically caused by sharp objects such as knives or saws but can also result from crushing injuries.
- Avulsion: An avulsion injury occurs when the nail and part of the nail bed are partially or completely pulled away from the rest of the nail bed. This is usually the result of a high-impact injury or crushing. Avulsions can be extremely painful and may require medical treatment.
Treatment for nail bed injuries depends on the severity of the injury. Minor injuries may heal on their own, while more severe cases may require medical attention. Doctors may remove the nail to repair the nail bed and reattach the nail or attach a synthetic nail if the natural nail is too damaged. Antibiotics may be prescribed to prevent infection, and in some cases, surgery may be necessary to correct deformities or severe injuries. It can take several weeks to several months for the nail to grow back completely, depending on the severity of the injury.

Nail infections
Paronychia can also be caused by irritation from water or chemicals, trauma to the nail bed or cuticle area, and certain medications, including retinoids, anti-cancer medications, HIV medications, and some antibiotics. Some bacterial infections that can cause paronychia include staph infections (caused by Staphylococcus aureus bacteria) and Streptococcus pyogenes.
Symptoms of paronychia include pain, swelling, and tenderness around the nail. The skin may be red and warm to the touch, and there may be pus buildup under the skin. An abscess may form and require drainage. If left untreated, the nail can grow abnormally and may have ridges or waves. It may also look yellow or green and become dry and brittle.
Fungal nail infections are another common type of nail infection. These infections cause the nail to become thick, discoloured, and brittle. They often affect the toenails but can also occur on the fingernails. Fungal nail infections usually start at the edge of the nail and slowly spread. They can be treated with antifungal nail medicine or tablets prescribed by a doctor.

Nail conditions
Infections
Infections around the fingernail or toenail, known as paronychia, can cause redness, swelling, and pain. Early diagnosis and treatment with soaks and antibiotics are essential. If an open sore forms, more extensive treatment is required. Bacterial nail infections can turn the nail greenish-black, and fungal infections can cause nail separation from the nail bed (onycholysis). Fungal infections can be treated with antifungal medications and proper nail care.
Melanoma
A new or changing dark streak on the nail could indicate acral lentiginous melanoma, the most serious type of skin cancer. It is crucial to see a dermatologist for an examination and potential early treatment.
Nail Separation (Onycholysis)
Onycholysis is when the nail separates from the nail bed, often due to injuries or fungal infections. It can cause discoloration, dents, crumbling nails, and hemorrhages. While there is no cure for reattaching the nail, treatment can prevent new nail growth from detaching. Keeping nails trimmed short and avoiding biting them can help prevent onycholysis.
Spoon-shaped Nails (Koilonychia)
Thin, spoon-shaped nails that dip down in the middle may indicate iron deficiency.
Thick, Overgrown Nails (Onychogryphosis)
Thick and overgrown nails, sometimes called "Ram's horn nails," can be caused by genetic factors or underlying conditions such as psoriasis, ichthyosis, or circulation problems. A podiatrist or dermatologist can help treat and manage this condition.
Beau's Lines
Deep grooves or gaps that run across the width of the nail indicate that something has slowed or stopped nail growth temporarily. This can be due to various factors, including severe eczema, injuries, fever, chemotherapy, or significant stress.
Nail Damage
Damaged nails, such as cracks or breaks, can occur due to various reasons, including trauma, ill-fitting shoes, or biting nails. To promote nail regrowth, it is essential to address any underlying causes, maintain a well-rounded diet, and practice good general health.

Nail care
The first step to achieving longer nail beds is to let your nails grow out. As your nails grow, the white tip becomes more prominent, elongating the nail bed. Protect your nails from cracks and breaks by using artificial nails while you wait for them to grow. Avoid using sharp objects to clean underneath your nails, as this can cause damage and separation of the nail plate from the nail bed. Instead, use a nail brush to clean the area under your nails.
You can also make your nail beds appear longer by pushing back your cuticles. Before doing so, soak your nails in warm water with a few drops of essential oil or cuticle oil for about five minutes. Then, dry your nails with a clean cloth and use a cuticle stick to gently push back the cuticles.
To maintain healthy nails, it is important to avoid certain habits that can damage them. Refrain from using your nails as tools, such as opening cans, as this can lead to chipping, splitting, or lifting of the nail bed. Protect your nails from excessive water exposure, as it can weaken them, causing them to split, peel, or break. Wear gloves when cleaning or washing dishes, and moisturize your hands afterward. Trim your toenails regularly, keeping them short to minimize the risk of trauma and injury.
Additionally, be cautious when dealing with ingrown toenails. Avoid "digging out" ingrown toenails, especially if they are infected or sore. Instead, seek treatment from a dermatologist. Wear properly fitting shoes and alternate between different pairs of shoes each day.
If you work with heavy objects or in construction, consider wearing steel-toe boots to protect your toes. Remember that certain injuries or illnesses can affect your nail matrix, impacting the growth and appearance of your nails. With proper treatment, healthy nails can often grow back.
