Strange Side Nails: Why Do They Grow That Way?

why do people have side nails growing out

Crooked nail growth is a common issue that can occur due to various factors. While the specific cause of side nail growth remains unclear, it is believed to be related to the shape of the nail bed. Additionally, certain health conditions, such as severe eczema or psoriasis, can affect nail growth and cause changes in the shape, texture, or color of nails. In some cases, nail abnormalities may be indicative of more serious underlying issues, such as nail matrix melanoma or infections like paronychia. Therefore, it is recommended to consult a dermatologist if you notice persistent changes in the shape, texture, or color of your nails, as early diagnosis and treatment can help prevent further complications.

Nail shape and growth direction

The shape of a person's nails and the direction of their growth can vary due to several factors, including genetics, nail care practices, and underlying health conditions. Here are some insights into nail shape and growth direction:

Nail Shape:

  • Genetic Factors: The shape of your nails, such as whether they are curved or straight, is often influenced by genetics. Some individuals naturally have nails that grow with a slight curve, while others may have straighter nails.
  • Nail Bed Shape: The shape of your nail bed can also contribute to the overall shape of your nails. As mentioned in a user comment, the way the nail bed is shaped can impact the direction of nail growth.
  • Nail Matrix: The nail matrix is the area underneath the nail where nail growth originates. Damage to the nail matrix, such as from an injury or certain health conditions, can affect nail shape and growth. For example, severe eczema can interfere with nail growth, resulting in changes to texture and shape.

Growth Direction:

  • Nail Growth Patterns: Nails typically grow in a direction that follows the contour of the fingertip. However, in some cases, nails may grow crooked or curved to the side. This variation in growth direction can be influenced by the shape of the nail bed or natural growth patterns unique to each individual.
  • Nail Care Practices: The way you care for your nails can also impact their growth direction. Improper trimming or filing can affect the way nails grow. For instance, trimming toenails straight across without following their natural curvature can lead to ingrown toenails.
  • Health Conditions: Certain health conditions can influence nail growth direction. For instance, onycholysis, a condition where the nail separates from the nail bed, can cause nails to grow unevenly or in different directions. This condition can result from injuries, fungal infections, or other underlying causes.

It's important to note that any significant changes in nail shape or growth direction could be a sign of underlying health issues. If you notice persistent abnormalities, it is recommended to consult a dermatologist or healthcare provider for proper diagnosis and treatment.

Nail matrix damage

The nail matrix is the "factory" where your body makes new fingernails and toenails. It is located at the base of the nail and is responsible for producing the cells that form your nail. The nail matrix has two parts: the germinal matrix and the sterile matrix. The germinal matrix is the area of the nail below the lunula (closest to the knuckle) and contributes to about 90% of nail production, giving a natural curvature to the nail. The sterile matrix is the area of the nail above the lunula and is responsible for the remaining 10% of cells that make up your nails, while also being crucial for keeping your nail attached to the underlying skin.

Injuries and certain health conditions can damage the nail matrix and interfere with nail growth. Trauma to the nail matrix can cause the production of new nail cells to stop for up to three weeks, and severe cases may result in long-term or permanent damage. Deep cuts or trauma to the germinal matrix at the nail's base may even lead to the nail never growing back. After an injury, nails often exhibit temporary changes during the healing process, such as bruising, ridges, discolouration, thickening, or a rough texture. These issues typically resolve as the nail grows and healthy cells replace the damaged area. However, severe injuries involving the nail matrix may result in lasting changes, including chronic thickening, uneven growth, or even complete and permanent nail loss.

Some health conditions that can affect the nail matrix include severe eczema, psoriasis, and subungual melanoma (nail matrix melanoma). Severe eczema can cause Beau's lines, pitting, and texture or colour changes in the nails. Nail psoriasis may lead to white lines, pitting, and crumbling of the nails. Subungual melanoma is a type of skin cancer that can cause brown or black discolouration on the nail. Any noticeable changes in the appearance or texture of the nails could indicate a nail matrix problem, and it is recommended to consult a healthcare provider for proper diagnosis and treatment.

In cases of severe nail matrix damage, proper medical care can help promote healthy nail growth. While it is rare for the nail matrix to be permanently damaged, preventing nail regrowth, proper treatment can often lead to the growth of healthy nails. With the right care, even if a nail falls off, it usually grows back.

Onycholysis (nail separation)

Onycholysis is a common nail disorder where the nail plate separates from the nail bed. It typically affects a single nail but can affect multiple nails in some cases. The condition usually does not cause any pain, but the underlying cause of onycholysis may be painful or irritating.

Onycholysis can be caused by trauma or injury to the nail or the nail matrix (the area where nails start to grow). This can happen due to several reasons, including bumping or hitting the nails, wearing shoes that are too small, or even keeping the nails in water for too long. Regular manicures, where tools like cuticle sticks or nail brushes are used, can also cause onycholysis. Additionally, activities such as tapping your nails on a hard surface over a long period can lead to this condition.

Chemical reactions to nail products like nail polish, nail gloss, nail hardener, and nail polish remover can also cause onycholysis. Furthermore, fungal infections, which occur when fungi get between the nail and the nail bed through cracks or cuts, can lead to onycholysis. Thick and yellow nails with white spots and streaks may indicate a fungal infection.

Certain medications, such as chemotherapy drugs, tetracycline, nonsteroidal anti-inflammatory drugs (NSAIDs), psoralens, and oral retinoids, can also cause onycholysis. Nail psoriasis, which affects up to 80% of people with psoriasis, can cause changes to the nail structure, including onycholysis. Iron deficiency and hyperthyroidism are other potential causes of onycholysis.

The treatment for onycholysis focuses on addressing the underlying cause. In some cases, cutting away the separated nail as it grows out may be sufficient. However, antifungal medications or discontinuing the use of certain nail products may be necessary. Keeping nails trimmed short can help prevent onycholysis by reducing the chances of nails catching on objects and pulling further off the nail beds.

Health conditions and infections

Several health conditions and infections can cause changes in the growth pattern of nails. Nails that grow out to the side may indicate an underlying health issue. Here are some possible causes:

Onycholysis

Onycholysis is a condition where the nail separates from its nail bed, often following an injury to the nail. It can also be caused by fungal infections, which can be identified through a fungal test. Treatment for onycholysis may involve cutting away the separated nail, taking antifungal medications, or discontinuing the use of certain nail products. Keeping nails short can help prevent onycholysis by reducing the risk of nails catching on objects and pulling further off the nail bed.

Paronychia

Paronychia is a common nail infection caused by bacteria entering the skin through cuts in the cuticle and nail fold. It can lead to pain, swelling, and tenderness around the nail, with symptoms typically appearing where the nail meets the skin. People with diabetes, compromised immune systems, or circulatory issues are at a higher risk of developing paronychia. Treatment for paronychia includes antibiotics to kill the infection and drainage of pus if an abscess forms.

Subungual Melanoma

Subungual melanoma is a type of skin cancer that affects the nail matrix. It is identified by brown or black discoloration on the nail. Treatment involves surgical removal of the affected area in the nail matrix and, if necessary, additional treatments such as chemotherapy or radiation.

Psoriasis and Eczema

Psoriasis and severe eczema can affect the nail matrix and interfere with nail growth. Nail psoriasis can cause white lines, pitting, and crumbling of the nails, while severe eczema can lead to Beau's lines, pitting, texture changes, and color changes.

Other Conditions

Other health conditions, such as thyroid disease, rheumatoid arthritis, and certain congenital conditions like nail-patella syndrome, can also affect nail growth and appearance. Additionally, serious illnesses like heart attacks, COVID-19, or pneumonia can cause Beau's lines (horizontal ridges) in the nails.

Nail care and cutting techniques

Crooked nail growth can be attributed to the shape of the nail bed. While there is no way to correct the direction of growth, you can file the sides of your nails to help the skin envelope and support the nail.

Nail care is important as it reflects your overall health. Here are some tips for maintaining healthy nails:

  • Keep your nails clean and dry to prevent bacteria and fungi from growing underneath your nails.
  • Trim your nails regularly, about once a week, to prevent them from growing too long and to keep them clean.
  • Cut your nails straight across with nail scissors or clippers, using a series of small cuts rather than one large cut to avoid bending and weakening your nails.
  • Round the nails slightly at the tips with a nail file or emery board to keep them strong and prevent snagging.
  • Always file your nails in the same direction, as filing back and forth can weaken them.
  • Avoid biting your nails and cuticles. Cuticles protect the nail root, and cutting or pushing them back can lead to infection.
  • Moisturize your nails after trimming, especially in dry conditions, to keep them flexible and prevent splitting.
  • Disinfect your nail clippers or scissors by scrubbing them with a brush soaked in isopropyl alcohol, then rinsing them with hot water and drying them completely.
  • If you notice any changes in the colour, texture, or shape of your nails, or if you experience pain, see a dermatologist as these could be signs of serious nail problems.
