The nail matrix is the growing spot for fingernails and toenails. It is made up of two parts: the germinal matrix, which is responsible for about 90% of nail growth, and the sterile matrix, which accounts for the remaining 10% of cells and is crucial for keeping the nail attached to the underlying skin. The nail matrix lies beneath the skin at the inner edge of the nail plate, and without it, no nail growth is possible. Injuries and certain health conditions, such as severe eczema or psoriasis, can damage the nail matrix and interfere with nail growth. Changes in nail appearance, such as dents, ridges, spots, or discolouration, could indicate a nail matrix problem.

What You'll Learn
The nail matrix is the nail growing spot
The nail matrix is the nail-growing spot. It is the actively growing tissue that generates cells, which then harden as they move outward from the nail root to the nail plate, forming the nail. The nail matrix is also known as the matrix unguis, keratogenous membrane, or onychostroma. It is part of the nail bed, which is located beneath the nail and contains nerves, lymph, and blood vessels. The matrix produces cells that become the nail plate, which is the visible hard nail area extending from the nail root to the free edge.
The nail matrix has two parts: the germinal matrix and the sterile matrix. The germinal matrix contributes to about 90% of nail growth, while the sterile matrix is responsible for the remaining 10% of cells that make up the nails. The sterile matrix, also known as the nail bed, plays a crucial role in keeping the nail attached to the underlying skin.
Injuries and certain health conditions can damage the nail matrix and interfere with nail growth. For example, severe eczema can affect the nail matrix and temporarily disrupt nail growth. Additionally, up to 80% of people with psoriasis may develop nail changes, including white lines, pitting, and crumbling. It is important to monitor your nails for any changes, as they can indicate underlying health issues.
If you notice any alterations in your nails, such as spots of colour, lines, ridges, or other abnormalities, it is advisable to consult a healthcare provider. They can determine whether it is a nail matrix problem or another issue and recommend appropriate treatment options.

Fingernails and toenails form in the nail matrix
The nail matrix is essential for healthy nail growth. Injuries or trauma to the nail matrix can cause nail growth to slow down or even stop temporarily. In some cases, deep cuts or trauma to the germinal matrix can result in permanent nail loss. Fingernail injuries are often caused by broken fingers, while toenail injuries can occur from dropping heavy objects. Certain health conditions, such as severe eczema, psoriasis, and fungal infections, can also affect the nail matrix and interfere with nail growth.
The appearance of your nails can provide important clues about your overall health. For example, yellow nails can indicate lung disease or rheumatoid arthritis, while horizontal ridges or lines may be a sign of Beau's lines, often caused by slowed nail growth due to fever, injury, chemotherapy, or stress. Changes in nail colour, such as dark streaks, could be a sign of melanoma, the most serious type of skin cancer. Therefore, it is important to monitor your nails and seek medical advice if you notice any significant changes or abnormalities.
The nail matrix is not easily visible, as most of it lies beneath the skin. The only visible part of the nail matrix is the lunula, the white crescent shape at the base of your nail. However, it is important to note that not everyone has visible lunulas, which is completely normal. The nail matrix is constantly producing new nail cells, ensuring the growth and renewal of your fingernails and toenails.

The nail matrix has two parts: the germinal matrix and the sterile matrix
The nail matrix is where your fingernails and toenails form. It is made of special cells that create new cells that become your fingernails or toenails. The nail matrix has two parts: the germinal matrix and the sterile matrix.
The germinal matrix is located under the base of your nail. It is responsible for about 90% of nail production, giving a natural curvature to the nail. It is the area of the nail below the lunula (the white crescent shape at the base of your nail), closest to the knuckle. The nail root and the germinal matrix are related, with the matrix lying beneath the skin at the inner edge of the nail plate. It is responsible for most of a nail's growth, as new cells grow and then advance forward to form the nail.
The sterile matrix, also known as the nail bed, is responsible for the remaining 10% of cells that make up your fingernails and toenails. It lies underneath the nail plate, attaching it to the distal phalanx. The nail bed provides a smooth surface for the growing nail plate to slide over. It extends from the edge of the nail root or lunula to the tissue known as the hyponychium. The nail bed contains blood vessels, nerves, and melanocytes that produce melanin. As the root grows, the nail moves down along the nail bed and adds material to the underside of the nail to make it thicker.
Injuries and certain health conditions can damage the nail matrix and interfere with nail growth. For example, a deep cut or trauma to the germinal matrix at the base of the nail can result in the nail never growing back. In addition, severe eczema can affect the nail matrix and cause Beau's lines, pitting, texture changes, and colour changes. Similarly, nail psoriasis can lead to white lines, pitting, and crumbling of the nails.

The nail matrix is located beneath the skin, at the inner edge of the nail plate. It is responsible for most of a nail's growth, with the nail root contributing to its length and the nail bed contributing to its thickness. The nail matrix has two parts: the germinal matrix and the sterile matrix. The germinal matrix contributes to about 90% of nail growth, while the sterile matrix is responsible for the remaining 10% and plays a crucial role in keeping the nail attached to the underlying skin.
Injuries and certain health conditions can damage the nail matrix and interfere with nail growth. Minor matrix damage can cause temporary changes in the appearance and texture of the nail. For example, severe eczema can affect the nail matrix and hinder nail growth, resulting in Beau's lines, pitting, and colour changes. Nail psoriasis, which affects up to 80% of people with psoriasis, can also cause white lines, pitting, and crumbling of the nails. Additionally, subungual melanoma, a type of skin cancer, can manifest as brown or black discolouration on the nail. Any changes in the appearance or texture of the nail could indicate a nail matrix problem, and it is advisable to seek medical care if such changes are observed.
Proper nail care is essential to maintain the health of the nail matrix and promote optimal nail growth. Keeping nails trimmed and avoiding biting them can help prevent issues such as onycholysis, where the nail separates from the nail bed. Additionally, being cautious when cleaning underneath the nails is crucial, as certain tools can break the skin and lead to infections. Avoiding irritant chemicals and products, such as nail polish, nail gloss, and nail hardener, can also help maintain nail health.

Minor damage to the nail matrix can change the nail's appearance
The nail matrix is a vital structure in the nail unit, responsible for nail growth and health. It is located beneath the skin, at the inner edge of the nail plate, and consists of two parts: the germinal matrix and the sterile matrix. The former contributes to about 90% of nail growth, while the latter accounts for the remaining 10% and is crucial for keeping the nail attached to the underlying skin.
Minor damage to the nail matrix can indeed alter the appearance of nails. This damage could be caused by mechanical or health-related reasons. Mechanical causes include injuries such as hitting or pinching a finger, wearing tight shoes, or using sharp tools for manicures. Health-related causes can be severe eczema, fungal infections, or illnesses like COVID-19.
Consequently, you may observe changes such as ridges, grooves, indentations, or lines on the nail surface. There could also be negative changes in the nail shape, with deeper grooves and ridges, and the nail becoming thinner and deformed. Discolouration may also occur, with yellowish stains or white spots on the nail surface. These symptoms indicate that something has interfered with the normal nail growth process.
It is important to note that proper nail care and protection can safeguard the nail matrix, promoting optimal nail growth. This includes practices such as maintaining nail hygiene, avoiding excessive pressure or trauma to the nails, and ensuring a well-balanced diet to support nail health.
