Nail psoriasis

This is often how nail psoriasis begins — a condition that is far less known than skin psoriasis.

Nail psoriasis is not just a cosmetic issue. It can interfere with working with your hands, cause pain, embarrassment, avoidance of social contact, and a constant feeling of uncertainty: what is happening to my body, and can it be stopped? Why do the nails change in this way? How can you distinguish nail psoriasis on the hands or feet from a fungal infection? Is it always associated with skin symptoms, and most importantly — what should you do about it?

What is nail psoriasis?

Nail psoriasis of the hands or feet is a chronic, non-infectious condition in which the immune system disrupts the normal formation of the nail plate and nail bed. As a result, the nail grows abnormally, and its structure and appearance change. It is important to understand that psoriasis is not contagious and is not related to poor hygiene. This condition can occur both in people who already have diagnosed skin psoriasis and as the only manifestation of the disease, which often makes timely diagnosis more difficult. The disease has a relapsing course, with periods of flare-ups and relative improvement.

The main causes and factors that may contribute to its development or exacerbation include:

• immune system dysfunction, when skin and nail cells renew too quickly;
• genetic predisposition — the presence of psoriasis in close relatives;
• chronic stress and psycho-emotional overload, which can act as triggers for flare-ups;
• nail injuries (trauma, constant pressure, aggressive manicure or pedicure);
• infections that may provoke flare-ups (but are not the cause of psoriasis);
• hormonal imbalances and metabolic factors that can influence the course of the disease;
• immune disturbances associated with systemic inflammation.

Understanding the causes of the disease is the first step toward proper diagnosis and choosing an effective treatment strategy for nail psoriasis.

What do nails look like in psoriasis?

Nail psoriasis can visually resemble a fungal infection, but these conditions have different causes and may even occur at the same time. Nail psoriasis on the hands or feet can present in various ways, depending on which part of the nail unit is affected. Changes often develop gradually and, without proper treatment, may progress.

So, what do nails affected by psoriasis look like?

Changes in the nail plate:

• the appearance of small pits or pinpoint depressions;
• thickening and uneven surface;
• brittleness, splitting, and fragility;
• loss of natural shine, the nail becomes dull.

Changes in nail color:

• yellowish, whitish, or grayish spots;
• the “oil drop” (or “oil stain”) effect — a translucent yellow area under the nail;
• darkening of certain areas.

Involvement of the nail bed:

• separation of the nail from the nail bed (onycholysis);
• discomfort or pain when pressing on the nail.

Associated features:

• a combination of different symptoms may appear on one or several nails at once;
• symptoms often follow a wave-like course, with flare-ups alternating with periods of improvement;
• in some cases, psoriasis occurs without visible skin symptoms.

The variety of manifestations makes the condition difficult to assess on your own and complicates choosing the correct treatment approach for nail psoriasis.

How does nail psoriasis begin?

Nail psoriasis on the hands or feet usually starts subtly. In the early stages, the changes may seem minor or temporary, so they are often ignored or mistaken for cosmetic defects, the effects of a manicure, or vitamin deficiencies. Because of this, few people consider how to treat nail psoriasis at this point.

Early signs that often go unnoticed:

• isolated small dots or pits on the surface;
• slight unevenness of the nail plate;
• the nail grows more slowly or changes its usual shape;
• the natural shine disappears, and the nails look “dull” or “tired.”

Early changes under the nail:

• the appearance of yellowish or light spots;
• a feeling that the nail has become denser or rougher;
• mild discomfort without obvious pain.

Features of the initial stage:

• changes may appear on just one nail rather than all at once;
• symptoms are often unstable — they may disappear and then return;
• at this stage, there may be no visible skin symptoms of psoriasis, which makes recognition more difficult.

That is why the onset of nail psoriasis often goes unnoticed, and the correct diagnosis is made later.

How to treat nail psoriasis?

Nail psoriasis is a chronic condition, so it is important to focus not on a complete cure, but on disease control, reducing symptoms, and achieving remission. The treatment plan is always individualized and depends on the severity of nail involvement, the presence of skin psoriasis, coexisting conditions, and the overall health of the patient.

Key principles of treatment

Treatment of nail psoriasis is usually комплекс and combines several approaches:

• reducing the inflammatory process;
• normalizing the growth of the nail plate;
• preventing nail separation and deformation;
• prolonging periods of remission.

Methods of treating nail psoriasis

The main treatment approaches include:

1. Topical therapy is the basic option for mild to moderate nail psoriasis. It involves applying medications directly to the nail plate and surrounding tissues. These treatments are aimed at reducing inflammation and normalizing keratinization processes. Due to the density of the nail plate, penetration is limited, so results develop gradually, requiring consistent and long-term use.
2. Systemic treatment is used in cases where nail psoriasis is severe, rapidly progressing, or associated with skin psoriasis or psoriatic arthritis. These therapies act on the immune mechanisms underlying the disease and require medical supervision.
3. Physiotherapy is used as an adjunct within комплекс treatment of nail psoriasis. It has a limited evidence base but may be applied as an additional method to help improve the course of the disease.
4. Lifestyle modification is an important component of managing nail psoriasis. Reducing stress, protecting nails from trauma, gentle care, and following general health recommendations can help decrease the frequency of flare-ups.

How to treat nail psoriasis

It is important to understand that there is no universal remedy for this condition. Medications for nail psoriasis may include:

• anti-inflammatory agents (including topical corticosteroids and calcineurin inhibitors);
• drugs that target immune mechanisms (systemic therapy, biological agents);
• in some cases — injectable methods (intralesional corticosteroid injections).

The specific medications, their form, and duration of use are determined by a doctor after evaluating the condition of the nails.

How to treat psoriasis under the nails

Psoriasis under the nails requires special attention, as the nail plate makes it difficult for medications to penetrate. In such cases, the focus is on:

• regularity of treatment;
• a prolonged course of therapy;
• combining topical and systemic methods.

Self-treatment or inconsistent use of remedies often does not bring results and may worsen the course of the disease.

What should absolutely be avoided in psoriasis?

Nail psoriasis can easily be confused with fungal infections or other nail dystrophies. Therefore, before deciding how to treat nail psoriasis, it is essential to undergo proper диагностика and receive professional recommendations. At the Leoderm Medical Center, treatment of nail psoriasis begins with accurate diagnosis and an individualized approach — without unnecessary risks or trial-and-error.

After the diagnosis is established, it is important not only to follow the prescribed treatment but also to avoid actions that may worsen the condition of the nails and trigger flare-ups, namely:

• self-medicating, especially using antifungal treatments without a confirmed fungal infection;
• injuring the nails — aggressive manicures, cutting too short, grinding or filing thickened areas;
• forcibly separating the nail, even if it is partially detached;
• frequent contact with harsh chemicals without protection (household cleaners, solvents);
• overloading the nail plate with decorative coatings without proper control;
• ignoring stress and overall health, as psycho-emotional strain often worsens the condition.

A properly selected treatment strategy can significantly improve the appearance of the nails, reduce discomfort, and restore confidence in everyday life. Booking a consultation is the first step toward the health and beauty of your hands. Dermatologists at the LeoDerm Medical Center will help identify the cause of the changes and choose how and with what to treat nail psoriasis according to an individualized plan.
