ou have tried the pharmacy treatments. You have filed the nail down. You have applied the drops every single day for months. And the nail still looks the same.
This is one of the most common frustrations we hear from patients at our clinics in Dublin 11 and Dublin 14. Fungal nail infections are stubborn. And most treatments people try at home simply cannot reach where the infection lives.
The good news is that effective treatment exists. But it requires understanding what you are actually dealing with and choosing an approach that matches the severity of your infection.
What Patients in Dublin Are Asking
Does fungal nail treatment actually work?
Yes, but only if the treatment can reach the infection. Most over-the-counter products sit on top of the nail. They cannot penetrate the nail plate to reach the fungus growing underneath and in the nail bed. This is why so many people feel like nothing works. It is not that treatment is impossible. It is that the wrong treatment was chosen for the type of infection present.
Other questions we hear regularly from patients in Blackrock, Finglas, and across Dublin include:
- Why does my fungal nail keep coming back after treatment?
- Is laser treatment for fungal nails worth it?
- How long does it take to get rid of a fungal nail infection?
What Is Actually Going On
A fungal nail infection is not just a surface problem. The fungus gets under the nail plate and into the nail bed. In some cases, it reaches the nail matrix, which is where the nail grows from.
This is why the infection is so hard to shift. The nail itself acts as a barrier. It protects the fungus from whatever you apply on top.
You will usually notice changes in the nail’s colour first. It may turn yellow, brown, or white. The nail often becomes thicker, more brittle, and can start to crumble at the edges. Sometimes there is an unpleasant smell.
The longer the infection has been present, the deeper it has likely travelled. And here is an important truth most people are not told: even if you successfully clear the infection, the nail may not return to exactly how it looked before. Once the nail matrix has been disrupted, the growth pattern can be permanently affected.
This does not mean treatment is pointless. It means expectations need to be realistic from the start.
Why It Is Not Improving
Most people start with pharmacy products. These include antifungal nail paints, drops, and creams. For very mild surface infections, these can sometimes help. But they require daily application for many months. Consistency is everything. Miss a few days and you are back to square one.
The bigger problem is that these products simply cannot penetrate a thickened nail. If the infection has spread beneath the nail plate, a topical treatment applied to the surface has almost no chance of reaching it.
Oral antifungal medication like terbinafine is considered the gold standard. It works from the inside out. But it must be taken for several months and some patients are reluctant due to potential effects on the liver. It is not suitable for everyone.
So many patients end up stuck in the middle. They have tried the weaker options without success. They do not want to take oral medication. And they assume nothing else exists.
The Foot Focus Approach
At Foot Focus Podiatry, we start every fungal nail case with a proper assessment. We examine the nail’s integrity, the colour, how far the discoloration extends, and whether the infection has reached the nail matrix.
This tells us whether the infection is treatable in clinic and which approach will give the best chance of success. We are always honest about expected outcomes. If the nail has been damaged for years, we will tell you what is realistically achievable.
For suitable candidates, we offer a combination approach that attacks the infection from multiple angles:
Class IV laser therapy penetrates the nail plate and reaches the fungal cells beneath. The laser energy oxidises the fungal element, causing it to die. This is not a single-session fix. It runs over several months with multiple clinic sessions. But it reaches areas that topical products cannot.
We combine this with Qurnail, a medical-grade topical treatment applied once weekly by the patient at home. This dual approach gives us the best chance of clearing the infection while the nail grows out.
Our combination treatment has a satisfaction rate of over 75%. We monitor nail growth throughout the treatment period and adjust the plan if needed.

What Proper Treatment Looks Like
Treatment for fungal nails is a commitment. There are no overnight solutions.
A realistic plan looks like this:
- Assessment to confirm the infection and establish how deep it has spread
- Honest conversation about what results are achievable for your specific nail
- Treatment sessions over three to four months, combining in-clinic laser therapy with home application of Qurnail
- Monitoring as the nail grows out, tracking progress and adjusting if needed
Patience matters. Toenails grow slowly. It can take nine to twelve months to see a completely new nail grow through. But with the right approach, you can stop the infection progressing and give the nail its best chance of recovery.
Frequently Asked Questions
How do I know if my nail is actually infected with fungus?
Discolouration, thickening, brittleness, and crumbling are common signs. A clinical assessment can confirm whether fungus is present and how severe the infection is.
Can I paint over a fungal nail?
Nail polish traps moisture and can make the infection worse. It also blocks any topical treatment from reaching the nail.
Is laser treatment for fungal nails painful?
Most patients feel a warming sensation during treatment. It is not painful and requires no anaesthetic.
Why did my fungal nail come back after treatment?
The original treatment may not have fully cleared the infection, or re-infection occurred. Fungal spores can live in shoes and socks.
How can I stop fungal nails from coming back?
Keep feet dry, rotate footwear, treat shoes with antifungal spray, and address any infection early before it spreads.
Conclusion
Fungal nail infections persist because most treatments cannot reach where the fungus actually lives. At Foot Focus Podiatry, one of Dublin’s largest podiatry providers, we use a combination of Class IV laser therapy and medical-grade topical treatment to target the infection properly and give your nail the best chance of recovery. If your fungal nail is not responding to pharmacy products, book an assessment at our North Dublin or South Dublin clinic.
