How to Get Rid of Nail Fungus: A Practical Guide for Adults

Why "Fast" Is the Wrong Word for Nail Fungus Treatment

The phrase "get rid of nail fungus fast" is everywhere online — and it sets the wrong expectation from the start. Here's the biology: toenails grow at approximately 1 to 1.5mm per month. For a toenail to be fully replaced by new, healthy growth takes 12 to 18 months. Fingernails are faster — roughly 3 to 4mm per month — but still require months of treatment to show full clearing.

This doesn't mean nothing is happening in the early weeks of treatment. It means that the results you are working toward are tied to nail growth cycles, not to how quickly an ingredient can kill fungal cells. The fungal cells may be neutralised relatively quickly with a well-formulated treatment, but the visible result — a clear, healthy nail — only emerges as new nail grows in from the base.

The most effective thing you can do is commit to a consistent, daily treatment routine and maintain it for three or more months without expecting to see dramatic changes in the first few weeks.

Step 1: Confirm You Actually Have Nail Fungus

Not every discoloured or thickened nail is caused by fungus. Other conditions — including nail psoriasis, nail trauma, lichen planus, and certain systemic conditions — can cause similar symptoms. Treating a non-fungal nail problem with an antifungal is unlikely to help and may delay the correct diagnosis.

Classic signs of nail fungus include:

• Yellow, brown, or white discolouration starting at the tip or edge of the nail
• Thickening of the nail plate
• Brittle, crumbly, or ragged nail edges
• Separation of the nail from the nail bed (onycholysis)
• A slightly unpleasant odour in severe cases
• Debris accumulating under the nail

If you are uncertain about your diagnosis, a visit to a GP, dermatologist, or podiatrist for nail clipping analysis can confirm the presence of fungal organisms. This is particularly important before starting prescription treatment.

Step 2: Understand Your Treatment Options

There are three main categories of nail fungus treatment, each with different risk profiles, evidence bases, and practical considerations:

Topical Antifungal Treatments (OTC and Prescription)

Applied directly to the affected nail. These range from over-the-counter products (tea tree oil based formulas, amorolfine lacquers in some countries) to prescription-strength nail lacquers like ciclopirox. The primary limitation of topicals is penetration — the nail plate is a natural barrier, and most formulas don't reach the nail bed effectively without a dedicated carrier system.

Products with penetrating carrier oils (such as Emu Oil) have an advantage here. DermaFix, for example, is specifically formulated around this challenge — see our full ingredient breakdown for details.

Oral Antifungal Medications (Prescription Only)

Terbinafine and itraconazole are the most commonly prescribed oral antifungals. They work systemically — reaching the nail bed via the bloodstream — and have a stronger clinical evidence base than topical treatments for severe infections. However, they carry risks including potential liver toxicity, drug interactions, and GI side effects. They require prescription and monitoring, and are generally reserved for moderate to severe cases.

Professional Procedures

In severe cases, nail avulsion (surgical or chemical removal of the nail) may be recommended alongside antifungal treatment. Laser therapy is also offered by some clinics, though the evidence base is more limited and costs can be significant.

Step 3: Optimise Your Daily Routine

Regardless of which treatment you use, the following daily habits significantly improve your chances of success:

Keep Nails Trimmed and Clean

Trim affected nails regularly to reduce the volume of infected nail tissue. File down thickened areas gently before applying topical treatment — this removes a physical barrier between the product and the nail bed. Always disinfect nail tools after use to prevent reinfection.

Keep Feet Dry

Fungi thrive in warm, moist environments. After bathing, dry your feet thoroughly — including between the toes. Consider using a separate towel for your feet if others in your household are present.

Wear Breathable Footwear

Synthetic materials trap moisture. Natural fibres (cotton, wool, leather) allow better airflow. Rotate your shoes to allow them to dry fully between wears. Use antifungal powder inside shoes if you are prone to athlete's foot, which often accompanies nail fungus.

Change Socks Daily (or More)

Cotton socks absorb moisture but hold it against the skin. Moisture-wicking athletic socks designed for foot health are a practical upgrade for anyone dealing with recurring fungal issues.

Avoid Walking Barefoot in Shared Spaces

Swimming pool surrounds, gym changing rooms, communal showers, and locker room floors are common transmission environments. Wearing flip-flops or sandals in these spaces substantially reduces your risk of picking up additional fungal contamination while you are treating an existing infection.

Step 4: Maintain Consistency Over Months, Not Days

The single most common reason nail fungus treatment fails — for people using appropriate products — is inconsistency. Applying a treatment a few times a week, or stopping after a few weeks because you don't see dramatic results, will not work. The treatment needs to maintain a sustained presence in the nail environment across multiple growth cycles.

Think of it this way: you are not just killing the current fungus — you are supporting the growth of new, healthy nail tissue that needs to replace the infected nail from the base outward. Every missed day is a day of less support for that process.

Step 5: Know When to See a Doctor

Self-treatment is appropriate for mild to moderate nail fungus in healthy adults. However, you should seek professional medical advice if:

• The infection is spreading beyond the nail to surrounding skin
• You are experiencing pain, swelling, or discharge
• You have diabetes or a compromised immune system
• The infection has not improved after three months of consistent topical treatment
• You are on medications that may interact with oral antifungals

Preventing Reinfection

Many people successfully clear nail fungus only to experience a recurrence within months. This usually happens because the environmental source of the infection was not addressed. Prevention requires ongoing hygiene habits — the same ones that support treatment. For a detailed guide, see our nail fungus prevention tips page.
