Expert fungal nail treatment and prevention at our foot care clinic in Vaasa. Effective solutions for all stages of nail fungus.

What Is Toenail Fungus?

Toenail fungus, medically known as onychomycosis, is a common fungal infection that affects the toenails. It is most often caused by dermatophyte fungi, though yeasts and moulds can also be responsible. The infection begins when fungi enter through small cracks in the nail or the surrounding skin.

Onychomycosis accounts for roughly half of all nail disorders and affects an estimated 10–14% of the general population. It becomes more common with age — up to 50% of people over 70 have some degree of fungal nail infection. While not dangerous in most cases, it can cause discomfort, embarrassment, and complications if left untreated, particularly for people with diabetes or weakened immune systems.

Signs & Symptoms

Toenail fungus develops gradually. Watch for these signs:

  • Thickened nails — the nail becomes noticeably thicker and harder to trim
  • Discolouration — yellow, brown, or white patches or streaks on the nail
  • Brittle, crumbly texture — the nail becomes fragile and breaks or crumbles easily
  • Distorted shape — the nail may warp, curl, or become irregular
  • Dark debris under the nail — a buildup of fungal matter beneath the nail plate
  • Slight foul odour — an unpleasant smell coming from the affected nail

In advanced cases, the nail may separate from the nail bed (onycholysis), causing pain and making the nail vulnerable to secondary bacterial infections.

Causes & Risk Factors

Toenail fungus is caused by various types of fungi, most commonly dermatophytes. Several factors increase your risk:

  • Warm, moist environments — fungi thrive in damp shoes, sweaty socks, public pools, and communal showers
  • Aging — reduced blood flow, slower nail growth, and years of fungal exposure increase risk with age
  • Diabetes — reduced circulation and immune response make diabetics especially vulnerable
  • Poor circulation — conditions like peripheral vascular disease reduce the body’s ability to fight infection in the toes
  • Weakened immune system — conditions or medications that suppress immune function increase susceptibility
  • Athlete’s foot connection — the same fungi cause athlete’s foot, and the infection often spreads from the skin to the nails
  • Nail injuries — damaged or lifted nails provide an entry point for fungal organisms
  • Walking barefoot — in public areas like gyms, pools, and locker rooms increases exposure to fungi
  • Excessive sweating (hyperhidrosis) — creates an ideal warm, moist environment for fungal growth

Treatment Options at ihohud

We offer comprehensive fungal nail assessment and treatment as part of our professional pedicure services:

Professional assessment

Every treatment begins with a thorough examination of the affected nails. We assess the type and severity of the infection and create a personalised treatment plan.

Urea-based nail treatment

We use professional-grade urea preparations to soften and break down the affected nail tissue. High-concentration urea (20–40%) is applied to the infected nail to gently dissolve the damaged, thickened portions. This painless process makes it easier to remove infected material and allows antifungal agents to penetrate more effectively. Urea treatment is offered as part of our pedicure services.

Topical antifungal treatment

After reducing the infected nail, we apply topical antifungal solutions directly to the nail bed and surrounding area. We can also recommend effective over-the-counter antifungal products for continued home use between appointments.

Fungal sample laboratory test

To confirm the diagnosis and identify the specific type of fungus, we can take a nail sample and send it to a certified laboratory for analysis. The fungal sample laboratory test costs €95 and provides accurate identification of the organism, ensuring the most effective treatment approach is selected.

Prescription medication via our in-house doctor

If the laboratory test confirms a fungal infection, our in-house doctor can write a prescription for oral antifungal medication (such as terbinafine or itraconazole) — no need for a separate GP visit. Oral treatment typically lasts 6–12 weeks, though full nail regrowth takes 9–12 months. This streamlined process means faster diagnosis and treatment under one roof.

Proper nail care during treatment

Throughout your treatment, we provide professional nail trimming and filing to keep affected nails manageable. Regular maintenance visits help us monitor progress and adjust the treatment plan as needed.

Self-Care & Home Treatment

Support your professional treatment with good daily habits:

  • Keep nails trimmed short — trim straight across and file down thickened areas to reduce fungal mass
  • Keep feet clean and dry — wash feet daily and dry thoroughly, especially between the toes
  • Use antifungal powder or spray — apply to feet and inside shoes to reduce fungal growth
  • Change socks daily — or more often if your feet sweat; choose moisture-wicking materials
  • Wear breathable shoes — avoid tight, synthetic footwear; alternate shoes to allow drying between wears
  • Don’t share nail clippers — use separate tools for infected and healthy nails, and disinfect after each use
  • Apply antifungal treatments consistently — follow the recommended schedule without skipping applications
  • Use OxySoak foot bath — our oxygen-enriched foot bath product helps maintain hygiene, deep-cleanses, and creates an environment unfavourable to fungal growth. Available in our shop
Patience is key: Toenails grow slowly (about 1mm per month). Even with effective treatment, it takes 9–12 months for a completely new, healthy nail to grow in. Don’t stop treatment early just because the nail looks better.

Prevention

Reduce your risk of developing or spreading toenail fungus:

  • Practise good foot hygiene — wash feet daily with soap and water, and dry thoroughly
  • Dry feet completely — pay special attention to the spaces between your toes where moisture collects
  • Wear flip-flops in public areas — always protect your feet in communal showers, pools, saunas, and locker rooms
  • Choose proper fitting shoes — ensure adequate toe room and breathable materials to reduce moisture buildup
  • Treat athlete’s foot promptly — since the same fungi cause both conditions, untreated athlete’s foot often spreads to the nails
  • Disinfect nail tools — clean clippers and files after each use, and never share them
  • Avoid nail polish on infected nails — polish traps moisture and prevents the nail from breathing
  • Replace old shoes — heavily worn shoes may harbour fungal spores; treat shoes with antifungal spray

When to See a Professional

Seek professional help if you experience any of the following:

  • The infection is spreading to other nails or showing no improvement with home treatment
  • You experience pain or discomfort from the thickened or distorted nail
  • You have diabetes or circulation problems — fungal infections can lead to serious complications
  • The nail is lifting from the nail bed (onycholysis)
  • The skin around the nail is red, swollen, or painful — this may indicate a secondary bacterial infection
  • You are unsure whether it is fungal — other conditions like psoriasis can look similar
Important for diabetics: If you have diabetes, any changes to your toenails should be assessed by a professional. Fungal infections in diabetic feet carry a higher risk of complications including secondary infections and ulceration. We offer specialised diabetic foot care.

Frequently Asked Questions

Treatment duration depends on the severity of the infection. Mild cases may respond to topical treatment within 3–6 months. Moderate to severe infections treated with oral medication typically require 6–12 weeks of medication, but complete nail regrowth takes 9–12 months. Patience and consistency are essential — stopping treatment early often leads to recurrence.

Yes. Toenail fungus can spread through direct contact or by sharing contaminated surfaces, shoes, socks, or nail tools. The fungi thrive in warm, moist environments like public showers, swimming pools, and locker rooms. You can also spread the infection from one nail to another on your own feet. Practise good hygiene and avoid sharing personal foot care items.

Some home remedies like tea tree oil and vinegar soaks have mild antifungal properties but are generally not strong enough to cure established infections. They may help as a supplementary measure alongside professional treatment. For persistent or moderate to severe infections, medically proven antifungal treatments are far more effective. We recommend consulting a professional rather than relying solely on home remedies.

Athlete’s foot and toenail fungus are caused by the same type of fungi (dermatophytes). Athlete’s foot affects the skin of the feet, and if left untreated, the infection frequently spreads to the toenails. Similarly, fungal nails can reinfect the surrounding skin. Treating both conditions simultaneously is important to prevent a cycle of reinfection.

It is best to avoid regular nail polish on infected nails. Polish creates a sealed, moist environment that can worsen the infection and prevents topical treatments from reaching the nail. If you want to cover the nail for cosmetic reasons, ask your foot care specialist about medicated antifungal nail lacquers that treat the fungus while providing some coverage.

Recurrence is possible, especially if the underlying risk factors are not addressed. Studies show that 10–25% of successfully treated cases experience reinfection. To minimise the risk, maintain good foot hygiene, keep feet dry, wear breathable shoes, treat athlete’s foot promptly, and consider using preventive antifungal products in shoes and on feet.
