What is nail fungus?
A nail that gradually turns yellow, thickens, cracks, or starts to lift off the nail bed – people often think it’s just a cosmetic issue.
But these changes are usually caused by a fungal infection that can spread if left untreated and damage the nail permanently.
Nail fungus is not dangerous, but stubborn, so it should be diagnosed and treated early.
Seeing a doctor is recommended if you …
- notice changes in one or more nails – such as thickening, discoloration, or brittleness
- suspect a fungal infection
- have already tried home remedies but haven’t seen improvement
- want treatment with medical products, tablets, or laser therapy
- wish to prevent the fungus from spreading to other nails or people

What happens during diagnosis and treatment of ingrown toenails?
First, our dermatologist carefully examines the affected nail and the surrounding area.
To identify the exact fungus, we usually take a sample – this is painless and done by scraping, nail shavings, or with a tiny drill.
The sample is analyzed under a microscope or in a lab test to clearly detect fungal germs.
Only then can the right treatment be selected.
What happens during nail fungus treatment?
Treatment depends on how severe it is:
If only a small area is affected, medicated nail polish or creams may be enough.
If several nails are thickened, brittle, or severely changed, medications may be needed – taken over several weeks.
Laser therapy may help destroy the fungus inside the nail.
The goal is to slowly clear the infection and allow a healthy nail to grow back.
How does nail fungus treatment work?
First consultation & examination:
We’ll talk with you about your symptoms, how long they’ve been going on, and any health conditions. The dermatologist examines the affected nail and takes a small sample.
Lab diagnosis
The sample is checked under a microscope or in the lab. This helps us reliably see if there’s a fungus involved and which kind, so we can choose the right treatment.
Personalized treatment recommendation
Depending on how severe it is, we may use creams, solutions, tablets, or laser therapy. Often, a combination is helpful.
Ongoing follow-up
We regularly monitor your progress and adjust the treatment if needed.

FAQ – Common questions about nail fungus treatment
What is nail fungus?
Nail fungus (medical term: onychomycosis) is an infection of the fingernails or toenails caused by fungi. The nail often becomes yellowish, thickened, brittle, or changes shape. Toenails, especially the big toe, are most commonly affected.
How do I recognize nail fungus?
Typical signs include discoloration (yellow, brown, or white), thickened or cracking nails, and a dull, rough nail surface. Without treatment, the fungus can spread to other nails.
Is nail fungus contagious?
Yes, nail fungus is contagious – especially in warm, damp places like pools, showers, or saunas. It can also spread through shared towels or nail clippers at home.
How is nail fungus treated?
Depending on how bad it is, we use medicated nail polish, creams, or oral tablets. In stubborn cases, laser therapy may help. A timely medical diagnosis is key.
How long does nail fungus treatment take?
Treatment takes patience: toenails grow slowly, so full recovery often takes 6 to 12 months. Applying the treatment regularly is essential for success.
Does laser therapy help with nail fungus?
Yes, laser therapy can help – especially for long-term or recurring infections. It’s usually added to a cream or tablet treatment.
Can nail fungus go away on its own?
Usually not. Without treatment, the fungus can continue to spread and cause more damage. Seeing a skin doctor is always a good idea.
How can I prevent nail fungus?
Keeping your feet dry and cared for is the best prevention. Wear breathable shoes, disinfect your footwear regularly, and use your own nail care tools. In public places: always wear shower shoes.
When should I see a doctor about nail changes?
If a nail becomes discolored, thick, brittle, or painful, it makes sense to see a specialist. A dermatologist can test for fungus and decide if treatment is needed.
