The nail matrix is the most important structure within the nail unit, as it is responsible for nail growth. New nail plate cells are created in the matrix, and as these new cells are formed, older cells are pushed forward and the nail plate grows. The nail matrix is located behind and under the base of the nail and is protected by a fold of skin called the proximal nail fold. Damage to the nail matrix is a common problem, resulting from mechanical injuries or improperly performed nail care procedures. Depending on the severity of the damage, the nail may grow back with small ridges or bumps, or it may not grow back at all.

Nail growth disorders
The nail matrix is the most important structure within the nail unit and is responsible for nail growth. As new cells are produced in the matrix, they move forward, harden, and form the nail plate. The nail plate grows as older cells are pushed outward. The nail matrix is located just below the nail fold, which protects it from injuries. However, damage to the matrix is a common problem, often resulting from mechanical injuries or improperly performed nail care procedures. This can lead to nail growth disorders, an unfavourable appearance, and pain.
Mechanical Injuries
Sharp injuries, such as a strong blow, crushing, or pinching the fingertip in a door, can cause mechanical damage to the nail matrix. This can result in inhibited growth, asymmetric nail growth, or onychomadesis (peeling of the nail plate and layering of subsequent nails). In severe cases, the nail may not grow back, or it may grow back with defects, such as a changed shape or uneven surface.
Improper Nail Care Procedures
Improper nail care procedures, such as cuticle picking, improper use of a drill, or aggressive chemical agents, can also damage the matrix. This can lead to a wavy nail plate, white spots, ridges, or weakened nails that are more susceptible to breakage or deformation.
Medical Conditions
Certain medical conditions can also affect nail growth and cause nail matrix damage. These include:
- Eczema: Severe eczema can interfere with nail growth, causing Beau's lines, pitting, and texture or colour changes.
- Psoriasis: Nail psoriasis can cause white lines, pitting, and crumbling of the nails.
- Subungual melanoma: A type of skin cancer that affects the nail matrix, causing brown or black discolouration.
Treatment
The treatment for nail matrix damage depends on the cause. Minor damage may heal on its own, allowing the nail to grow back without any noticeable issues. More severe damage may require medical treatment to ensure proper nail growth. This can include medication, such as antifungal pills or injections, nail trephination to drain blood and relieve pressure, or surgery to remove melanoma. Proper nail care and a well-rounded diet can also support nail health and growth.

Treatment and recovery
If you suspect damage to your nail matrix, it is important to consult a specialist who can assess the severity of the damage and determine the appropriate treatment. In some cases, minor damage to the nail matrix may heal on its own, and the nail will grow back without any noticeable issues. However, more severe damage can result in permanent deformities in the nail plate.
- Bruise under the nail or subungual hematoma: A procedure called nail trephination can be performed to drain the trapped blood and relieve pain. This procedure must be done within 48 hours of the injury, before the blood clots.
- Subungual melanoma: This is a type of skin cancer that affects the nail matrix. It typically presents as brown or black discoloration on the nail. Surgical removal of the affected area in the nail matrix and under the nail is necessary.
- Nail fungus: Prescription antifungal pills are the typical treatment for nail fungus.
- Nail psoriasis: Medications, including pills, injections, or topical treatments, can help manage nail psoriasis, which can cause white lines, pitting, and crumbling of the nails.
- Infections: Antibiotics may be prescribed to prevent or treat infections in the nail bed.
- Bone fractures: An X-ray may be necessary to check for bone fractures associated with nail bed injuries.
- Minor nail bed injuries: Bandages and ice packs can help treat minor injuries. Prompt treatment can ensure the nail bed heals appropriately and the nail grows back smoothly.
- Severely damaged nails: In some cases, the nail may be too damaged to be saved, and a doctor may remove it to repair the nail bed and matrix. Stitches may be used to repair lacerations to the nail bed, and a synthetic nail may be attached to protect and support the area while the new nail grows.
The speed of nail growth and recovery after matrix damage depends on the severity of the injury and how quickly treatment is initiated. It can take anywhere from 6 to 12 months for the nail to return to its pre-injury state. During this time, you can support nail plate regeneration with home care methods, such as using regenerating creams, maintaining a nutrient-rich diet, and using nail conditioners.

Causes of damage
The most common cause of nail matrix damage is mechanical damage, which can occur as a result of a sharp injury, a strong blow, pinching the fingertip in a door, or crushing with a heavy object. In addition, certain habits and improperly performed care procedures can also lead to matrix damage. For instance, improper cuticle work using a cuticle pusher or drill can cause damage to the matrix. Similarly, UV gel manicures that are improperly performed or removed can also cause nail damage. This includes applying too many layers of UV polish, which weigh down the nail plate, and scraping or peeling off the UV polish.
Health-related causes can also damage the nail matrix. Infections, such as bacterial, fungal, or viral infections, can trigger inflammation of the matrix, weakening the nail. Dermatological conditions such as psoriasis, eczema, and subungual melanoma can also cause matrix damage. Nutritional deficiencies, particularly in biotin, zinc, and iron, can also lead to changes in nails and matrix damage.
Furthermore, injuries to the nail bed, which is the area under the nail plate, can also cause matrix damage. A subungual hematoma, which looks like a bruise, can form when small blood vessels under the nail bed leak, causing blood to pool between the nail and the nail bed. This usually occurs when the tips of the fingers or toes have been crushed or subjected to a heavy impact.

Home remedies
- Bandages and ice packs: Applying bandages and ice packs immediately after an injury can help reduce swelling and pain. This prompt treatment can also help ensure that the nail bed heals smoothly, creating an optimal surface for nail regrowth.
- Nail trephination: While this procedure is typically performed by a medical professional, it can be done at home if done within 48 hours of the injury. Nail trephination involves making a small hole in the nail to drain pooling blood, providing pain relief and facilitating proper nail growth.
- Regenerating creams: Consulting a podiatrist or dermatologist for recommendations on regenerating creams or ointments can aid in the healing process. These specialized creams can support the regeneration of the nail plate and nail bed.
- Nutrition and supplements: A well-rounded diet rich in nutrients that support nail health can promote stronger nails. This includes consuming vitamins A, C, E, and biotin through dietary sources or supplements.
- Nail conditioners: Using nail conditioners and avoiding aggressive chemical agents can help support the external care of the nail plate.
- Proper nail care: Practicing proper nail care techniques, such as trimming nails correctly and avoiding manipulation of the cuticle, can prevent further damage to the nail matrix.
It is important to remember that home remedies should be used consistently and in conjunction with medical advice for optimal results. The recovery time for a damaged nail matrix can vary, typically taking several weeks to a few months for the nail to regrow and return to its pre-injury state.

Medical procedures
The nail matrix is the most important structure within the nail unit and is responsible for nail growth. The nail matrix is located behind and under the base of the nail, protected by the proximal nail fold. It is susceptible to damage from mechanical injuries, such as a sharp blow or crush injury, or improperly performed nail care procedures.
If the nail matrix is damaged, the nail may grow back with defects, such as ridges, dents, or an uneven surface. In cases of severe damage, the nail may not grow back at all, or it may be permanently deformed. Treatment for nail matrix damage depends on the cause and severity of the injury.
- Trephination: This procedure is performed for a subungual hematoma, which is a bruise under the nail caused by blood pooling between the nail and the nail bed. Trephination involves drilling a small hole in the nail to drain the blood and relieve pressure. It must be performed within 48 hours of the injury, before the blood clots.
- Nail removal and repair: If the nail is severely damaged or torn, it may need to be removed. The doctor will then repair the nail bed and matrix to prepare for nail regrowth. Stitches may be used to repair any lacerations to the nail bed.
- Synthetic nail attachment: In some cases, the doctor may attach a synthetic nail to protect the nail bed and support nail regrowth. As the new nail grows, the synthetic nail is gradually pushed forward.
- Minor surgical procedures: In some cases, a minor surgical procedure on the nail bed may be performed to improve the nail's appearance. This may involve removing the affected area in the nail matrix and under the nail.
- Medication: Certain nail conditions, such as nail fungus or psoriasis, can be treated with medication. Prescription antifungal pills are typically used for nail fungus, while nail psoriasis may be managed with pills, injections, or topical treatments.
It is important to note that the speed of nail regrowth and the return to its pre-injury state depend on the severity of the damage and the promptness of treatment. In general, fingernails can take 3-6 months to completely regrow, while toenails may take longer. During this time, it is recommended to support nail health with a well-rounded diet, including vitamins A, C, E, and biotin.
