Small dimples or pits on your fingernails or toenails are known as nail pitting. This condition can be a sign of an underlying health issue, such as psoriasis, eczema, or joint inflammation. Psoriasis, a common skin condition, causes skin cells to build up rapidly, leading to red and scaly skin. It can also cause nail changes, including pitting, thickening, and separation from the nail bed. Eczema and alopecia areata (hair loss) are other potential causes of nail pitting. While nail pitting may not always be a cause for concern, it is recommended to consult a doctor or dermatologist to rule out any underlying conditions and receive an accurate diagnosis.

What You'll Learn
Nail pitting
Psoriasis
Atopic Dermatitis/Eczema
Atopic dermatitis, also known as eczema, is another potential cause of nail pitting. It can lead to inflammation and irritation of the skin, nails, and mucous membranes. Eczema can run in families, and nail pitting may be observed in individuals with a long history of the condition.
Alopecia Areata
Alopecia areata is a condition that primarily causes hair loss, but it can also result in nail changes, including nail pitting. Research indicates that about 20% of people with alopecia areata experience nail pitting.
Reactive Arthritis
Reactive arthritis, previously known as Reiter's syndrome, is a type of bacterial infection that can affect the eyes, genitals, skin, and urinary tract. It is associated with nail pitting and may cause abdominal pain, conjunctivitis, diarrhea, and joint pain or stiffness.
In addition, other factors that may contribute to nail pitting include:
- Age: Research suggests that individuals over the age of 40 experience nail pitting twice as often as those under 20.
- Genetics: Certain genetic conditions, such as incontinentia pigmenti and Bloch-Sulzberger syndrome, can increase the likelihood of nail pitting.
- Stress: While it is not a direct cause, stress can exacerbate conditions like psoriasis and lead to nail pitting.
- Mineral deficiencies: Deficiencies in minerals like zinc can contribute to the development of white spots on the nails, which may be mistaken for nail pitting.
If you notice persistent or concerning nail pitting, it is recommended to consult a healthcare professional for further evaluation and appropriate diagnosis.

Psoriasis
Dimples on your fingernails are often referred to as nail pitting. This is a common symptom of nail psoriasis, an autoimmune condition that affects the fingernails and toenails. It causes discoloration, pitting, and changes in nail structure. While it is not a fungus, it can lead to a fungal nail infection.
Nail psoriasis is characterised by the appearance of pits or small depressions in the nails, which can range in size from 0.4mm to 2mm. These pits can be shallow or deep and may appear as white spots or marks. They can affect one or more nails, with some people experiencing more than 10 pits per nail. In addition to pitting, nail psoriasis can cause nail discolouration, with the nail bed appearing yellow, red, pink, brown, grey, or purple.
Other symptoms of nail psoriasis include changes in nail structure, such as the development of horizontal grooves (Beau's lines) and thinning of the nails, which can lead to crumbling. The thick layer of skin underneath the nail may also peel and slowly separate from the nail bed (onycholysis), resulting in loose nails. In severe cases, nail psoriasis can cause pain and tenderness, making it difficult to move the affected fingers and toes and perform daily activities.
Nail psoriasis is often associated with psoriasis on other parts of the body, but it can also occur without any other signs of the condition. It is important to monitor your nails for any changes and consult a dermatologist if you notice any symptoms. Early treatment can help prevent nail psoriasis from worsening and reduce its impact on your life.
There are several treatment options available for nail psoriasis, including corticosteroid creams, ointments, or nail polish that need to be applied directly to the affected area. In more severe cases, oral medications, medicine injections, or systemic medications that work throughout the body may be prescribed. Phototherapy using ultraviolet light is another potential treatment option for nail psoriasis.

Alopecia areata
Dimples on your fingernails are known as nail pitting. This is a common symptom of nail psoriasis, which affects around half of people with the condition. However, nail pitting can also be a sign of other underlying conditions, such as dermatitis and autoimmune diseases. If you notice dimples on your fingernails, it is advisable to consult a doctor.
Now, onto the topic of Alopecia Areata:
Who is Affected by Alopecia Areata?
Types of Alopecia Areata:
- Patchy alopecia areata: This is the most common type, characterized by hair loss in one or more coin-sized patches on the scalp or other parts of the body.
- Alopecia totalis: Individuals with this type experience loss of nearly all hair on their scalp.
- Alopecia universalis: This is a rare form of alopecia areata, resulting in a complete or nearly complete loss of hair on the scalp, face, and the rest of the body.
Treatment and Support:
Currently, there is no cure for alopecia areata, but treatments are available to help hair grow back more quickly. Resources are also available to help individuals cope with the emotional and psychological aspects of hair loss. Support groups and mentorship programs, such as the National Alopecia Areata Foundation (NAAF), offer guidance, connection, and community to those living with alopecia areata.

Eczema
Dimples on the fingernails, also known as nail pitting, can be a symptom of eczema. This condition is characterised by red, itchy skin and can affect any area of the body. It is also called atopic dermatitis.
Nail pitting is a common symptom of eczema, with around 10% of people experiencing it. It can cause small dents in the nails, as if they have been hit with a sharp object. These dents can be a sign of underlying inflammation in the nail matrix, which is the part of the nail responsible for growth. In addition to pitting, eczema can cause nails to become grooved, thin, and brittle. It may also lead to crumbling nails or onycholysis, a condition where the nail separates from the skin.
If you notice dimples on your fingernails, it is important to consult a dermatologist or healthcare provider. They can perform tests to rule out other health conditions and provide a proper diagnosis. Treatment for nail eczema may involve avoiding triggers, such as stress or certain soaps, and using topical steroids to reduce inflammation and improve symptoms.
In addition to eczema, nail pitting can also be caused by other conditions such as psoriasis, alopecia areata, and reactive arthritis. It is often related to autoimmune conditions and can be a sign of underlying inflammation or other health issues. Therefore, it is important to seek medical advice if you notice any changes in your nails.

Psoriatic arthritis
Dimples on the fingernails, also known as nail pitting, can be a sign of nail psoriasis, which is an early symptom of psoriatic arthritis (PsA). PsA is a type of inflammatory arthritis that occurs in some people with psoriasis, a condition that causes the overproduction of skin cells, resulting in dry, red patches with thick, silvery scales.
Nail pitting is characterised by small pits or depressions in the fingernails or toenails, which can appear as shallow or deep holes and can resemble white spots or marks. It is often related to skin conditions, such as psoriasis, which can cause inflammation and patches of red, scaly skin. Up to 50% of people with psoriasis experience changes in their nails, and it is more common in those with a family history of psoriasis.
In addition to nail pitting, PsA can cause a variety of nail issues, including flaking, ridges, and thickening of the nails. It can also lead to onycholysis, where the nail separates from the skin, and subungual hyperkeratosis, where a chalk-like material builds up under the nail, causing tenderness and discomfort. Beau's lines, which are horizontal grooves across the nails, can also be indicative of PsA.
Treatment for nail psoriasis can be challenging due to the slow growth of nails. Topical treatments, such as steroid creams and ointments, can be prescribed, but they must reach the nail bed and matrix to be effective, which can be difficult. In more severe cases, medicine injections or oral medications may be necessary. Light therapy (phototherapy) and antifungal medications may also be used to target nail psoriasis and any associated infections.
While nail pitting may be a sign of PsA, it can also be caused by other factors, such as mineral deficiencies or fungal infections. If you notice dimples on your fingernails or any other nail changes, it is advisable to consult a doctor for a proper diagnosis.
