Fungal Infections vs. Nail Psoriasis: What You Need to Know for Proper Treatment

Nail conditions can be both distressing and challenging to manage. Two common nail conditions that often cause confusion are fungal infections and nail psoriasis. Understanding the differences between these two conditions is crucial for accurate diagnosis and effective treatment. In this article, we will explore the causes, symptoms, and treatment options for nail fungus, as well as nail psoriasis, providing you with the necessary knowledge to navigate these conditions and seek the appropriate treatment for optimal nail health.

1. Understanding Nail Fungus

Nail fungus, also known as onychomycosis, is a fungal infection that affects the nails. Fungi, such as dermatophytes, yeasts, or molds, are the primary culprits behind nail fungus. These fungi thrive in warm, moist environments, making nails an ideal breeding ground. Several factors contribute to the development of nail fungus:

  • Prolonged exposure to damp environments, such as swimming pools, showers, or sweaty shoes
  • Injury or damage to the nail, creating an entry point for fungi
  • Wearing tight-fitting shoes that don’t allow for proper ventilation
  • Having a weakened immune system due to conditions like diabetes or HIV
  • Poor circulation, which can impede the body’s ability to fight off infections

Understanding these causes can help individuals take preventive measures and reduce the risk of nail fungus.

2. Nail Fungus Symptoms and Impact on Daily Life

Recognizing the symptoms of nail fungus is crucial for early detection and prompt treatment. Common signs and symptoms of nail fungus include:

  • Thickened nails that may become brittle or crumbly
  • Discoloration of the nails, usually yellowish or brownish
  • Deformation or an irregular shape of the nail
  • Build-up of debris under the nail
  • Unpleasant odor
  • Pain or discomfort

Nail fungus can significantly impact an individual’s daily life. It can cause self-consciousness and embarrassment, leading to a decrease in self-esteem. Physical discomfort may make simple tasks like walking or wearing shoes uncomfortable. Moreover, nail fungus can spread from one nail to another or even to other individuals. Sharing personal items like nail clippers, towels, or shoes can facilitate the transmission of the infection. If left untreated, nail fungus can persist for months or even years. Therefore, seeking appropriate treatment is crucial to prevent further complications and achieve a full recovery.

3. Treatment Options for Nail Fungus

Various treatment options are available for nail fungus, each with its own benefits and considerations:

Over-the-Counter Medications:

Over-the-counter antifungal creams, ointments, and nail polishes can be effective for mild to moderate cases of nail fungus. These products usually contain ingredients like clotrimazole or undecylenic acid, which help combat the infection. It’s important to carefully follow the instructions and apply the medication consistently for optimal results.

Prescription Medications:

In more severe or persistent cases, a healthcare professional may prescribe oral antifungal medications. These prescription drugs, such as terbinafine or itraconazole, work from within the body to eliminate the fungal infection. They are typically taken for a few weeks or months, and periodic blood tests may be necessary to monitor potential side effects.

Nail Removal:

In cases of severe or recurring nail fungus, a healthcare professional may recommend nail removal. This procedure allows for direct treatment of the affected area and promotes the growth of a healthy nail.

Alternative and Natural Remedies:

Some individuals prefer to explore natural remedies as an alternative or complementary treatment for nail fungus. Tea tree oil, vinegar, and hydrogen peroxide are among the commonly suggested natural remedies. While research on their effectiveness is limited, they may be worth considering for mild cases or as part of a preventive regimen.

It’s important to consult with a healthcare professional before starting any treatment to determine the most suitable option based on the severity of the infection and individual circumstances.

4. Understanding Nail Psoriasis

Nail psoriasis is a chronic autoimmune condition that affects the nails. It is a subtype of psoriasis, a skin condition characterized by inflammation and scaling. The exact cause of nail psoriasis is unknown, but it is believed to involve an abnormal immune response. Factors such as genetics and environmental triggers may play a role.

Symptoms of Nail Psoriasis:

The symptoms of nail psoriasis may vary from person to person, but common signs include:

  • Pitting: The development of small depressions or pits on the nail surface
  • Discoloration: Nails may appear yellowish-brown or have white spots
  • Thickening: Nails may become thick and may separate from the nail bed
  • Cracking: Nails may develop cracks or fissures
  • Onycholysis: The nail may lift or detach from the nail bed

Nail psoriasis can cause significant discomfort and affect the quality of life. It can make performing daily tasks difficult, such as gripping objects or typing on a keyboard. The appearance of the nails may also lead to self-consciousness and impact self-esteem.

5. Treatment Options for Nail Psoriasis

The treatment of nail psoriasis aims to manage symptoms and improve the appearance of the nails. Treatment options include:

Topical Medications:

Topical medications, such as corticosteroids or vitamin D analogs, can be applied directly to the affected nails to reduce inflammation and promote healing. These medications are available in the form of creams, ointments, or solutions.

Systemic Medications:

In severe cases of nail psoriasis, oral or injectable medications may be prescribed. These medications work from within the body to suppress the abnormal immune response and reduce inflammation.


Phototherapy involves exposing the affected nails to ultraviolet (UV) light. This treatment can help improve the appearance and condition of the nails by reducing inflammation and promoting normal cell growth.

Protective Measures:

Protective measures, such as wearing gloves or avoiding trauma to the nails, can help prevent further damage and protect the nails from external irritants.

6. Prevention and Self-Care

While complete prevention of nail fungus and nail psoriasis may not be possible, there are steps you can take to minimize the risk and manage symptoms:

Practice Good Nail Hygiene:

  • Keep your nails clean and dry.
  • Trim your nails regularly, and avoid biting or picking at them.
  • Avoid using sharp or pointed objects to clean under your nails, as it can cause injury and increase the risk of infection.

Moisturize and Protect:

  • Apply moisturizers to your nails and cuticles to keep them hydrated and prevent dryness and cracking.
  • Use gloves when performing tasks that involve prolonged exposure to water or chemicals.

Manage Stress:

Stress can exacerbate symptoms of nail psoriasis. Implement stress-management techniques, such as relaxation exercises, meditation, or engaging in activities you enjoy.

Avoid Triggers:

Identify and avoid triggers that worsen your symptoms. These triggers can vary from person to person and may include certain foods, environmental factors, or activities.

Consult with a Dermatologist:

If you suspect you have nail psoriasis or are experiencing symptoms, consult with a dermatologist. They can provide an accurate diagnosis and recommend the most suitable treatment options based on your specific condition.


Understanding the differences between nail fungus and nail psoriasis is essential for proper diagnosis and treatment. Nail fungus is a fungal infection that can cause nail thickening, discoloration, and discomfort. On the other hand, nail psoriasis is an autoimmune condition characterized by pitting, thickening, and other nail changes. By knowing the symptoms and available treatment options for each condition, you can seek appropriate care and achieve healthier nails.

Remember, prevention is key. Practice good nail hygiene, moisturize and protect your nails, and manage stress to minimize the risk of developing these conditions. If you suspect you have nail fungus or nail psoriasis, consult with a healthcare professional or dermatologist for an accurate diagnosis and personalized treatment plan. With proper care and guidance, you can maintain healthy and beautiful nails.
