Is It Really Nail Fungus? Where Does a Nail Technician’s Role End and When Should the Client Be Referred to a Specialist?
Is It Really Nail Fungus? Where Does a Nail Technician’s Role End and When Should the Client Be Referred to a Specialist?
A change in nail color, lifting of the nail plate, increased brittleness or unusual discoloration may look obvious at first glance. In practice, however, the situation is often far less clear.
A professional nail technician should be able to recognize that something about a nail looks or behaves unusually. She does not, however, need to make a medical diagnosis – and should not do so.
The ability to recognize the boundary between professional salon care and a condition that should be assessed by a medical specialist is an important part of truly professional work.
Why did we write this article?
The inspiration came from a real customer question we received at DENATO:
“Hello, do you have a salon in Prague where brittle and possibly fungal nails can be treated?”
At first glance, it seems like a simple question. In reality, it clearly shows how easily cosmetic care can be confused with the treatment of a health problem.
We could recommend a product for strengthening natural nails or a system intended for the care of problem nails. But if we do not know why the nail has changed, it is not right to start by choosing a product.
The first step is to determine whether the condition is suitable for professional salon care or whether the client should first undergo specialist assessment. This boundary is exactly what this article is about.
What can a nail technician actually recognize on the nail?
An experienced nail technician should be able to recognize when a nail does not look or behave normally.
She may observe, for example:
- a change in the color of the nail plate,
- thickening or, conversely, thinning of the nail plate,
- splitting and increased brittleness,
- changes in structure,
- accumulation of keratinized tissue,
- changes in the surrounding skin,
- separation of the nail plate from the nail bed – onycholysis.
These are all observable changes in the nail, not automatically a diagnosis of their cause.
This distinction is essential.
A nail technician can describe what she sees. She does not have to turn that observation into a diagnosis.
“That’s nail fungus.” Really?
In salon practice, the term “fungus” is sometimes used too quickly.
The nail changes color – fungus.
It separates from the nail bed – fungus.
It thickens, starts to crumble or changes appear underneath it – fungus.
The appearance of a nail can tell us that something is not right. It does not always tell us reliably why.
If there is a suspicion of fungal or another disease, it is not the nail technician’s role to confirm that diagnosis.
The correct step is to recommend specialist assessment.
Saying “this should be assessed by a doctor first” is not a failure of professionalism. It is part of professional practice.
Why is simply covering the nail not the right solution?
This is where one of the biggest problems in salon practice can arise.
A client does not always come because she wants to understand the cause of the change. Often, she simply wants the nail to look nice again.
“Can’t we just put gel over it?”
But an aesthetic covering does not address the cause of the problem.
If we are uncertain about the condition of the nail, immediate appearance should not take priority over safe professional practice.
The nail can be enhanced later. First, we need to know whether it is appropriate and safe to work on it at all.
How should a nail technician proceed when a client arrives with a problem nail?
There is no need to play dermatologist. It is, however, useful to work systematically.
- First, I look carefully.
What do the nail plate, nail bed and surrounding skin look like? Is the change present on one nail or several? Do I see a change in color, structure, lifting of the nail plate or other unusual signs? - I ask questions.
How long has the change been present? Was there an injury beforehand? Did it appear suddenly? Is the nail painful? Has the client already seen a doctor? Does she know what may have caused the change? - I do not assign a cause based on appearance alone.
I can describe what I see. I do not need to turn it into a diagnosis. - If I am uncertain, I do not cover the nail.
If I suspect that the change may be related to a disease, I recommend specialist assessment first. - Only then do I choose the appropriate care.
If the condition is suitable for salon care, I can choose care for the nail plate, the nail bed or a combination of both depending on the specific situation.
Refusing a service can sometimes mean doing the job properly
After many years in the nail industry, we are used to looking for solutions.
Which material should I use? How can I repair the nail? How can I strengthen it? What can I apply to make it look better?
But experience also means recognizing when we should not apply anything yet.
A professional nail technician does not need to be able to treat every change she sees on a client’s nails. She does not always need to know the exact cause either.
She should, however, work safely, understand her limits and know when it is more appropriate to recommend specialist assessment instead of another product.
Our goal should not be only to create a beautiful nail and cosmetically hide the problem. Our goal should also be to know when and under what conditions it is safe to work on that nail at all.
Where should the client be referred, or who can the issue be discussed with?
If there is a suspicion of fungal or another nail disease, there are several professionals the client can be referred to.
However, they have different areas of competence. Some can diagnose and initiate medical treatment, while others can help with professional mechanical care or follow-up care.
General practitioner
A general practitioner can perform an initial assessment of the nail, recommend the next steps and, in some cases, begin treatment.
If the finding is unclear, more extensive, recurrent or complicated, the client may be referred to a dermatologist.
Dermatologist
A dermatologist is the main medical specialist for diseases of the skin and nails.
They can determine whether the changes are consistent with a fungal disease, perform or recommend the necessary examinations and determine appropriate therapy based on the findings.
Depending on the specific case, treatment may be topical or systemic.
Surgeon
A surgeon is not usually the first specialist to see when nail fungus is suspected.
Surgical care is more relevant when complications require a surgical solution, for example severe pain, an ingrown nail, inflammatory complications or another condition that cannot be managed conservatively.
The doctor always decides on the appropriate procedure based on the current condition.
Pedicurist or podology-focused foot care specialist
An experienced pedicurist, particularly one specializing in instrument-assisted foot care and problem nails, can be an important part of overall care.
Within the limits of their professional competence, they can mechanically treat the nail, for example by removing loose or damaged areas or reducing thickened nail material.
Such care can also support the subsequent treatment or care recommended by a doctor.
It is important, however, to distinguish between professional nail care and the treatment of a disease.
A pedicurist does not make a medical diagnosis, prescribe medication or replace a dermatologist.
Pharmacist
A pharmacist can be a useful source of advice, especially when selecting over-the-counter products.
They can explain how to use them correctly, emphasize the importance of regular and sufficiently long application and advise on hygiene measures.
However, if the nail condition is unclear, does not improve over time, becomes worse or affects a larger area, a visit to the pharmacy does not replace a specialist medical examination.
So where does the nail technician’s role fit in?
This brings us back to the nail salon.
It is not the nail technician’s job to decide what disease the client has.
Her role is to:
- notice that the condition of the nail is not normal,
- safely assess whether she can work on it,
- avoid simply covering a suspicious condition,
- and know where to refer the client if there is any doubt.
Fungal nail disease is more common on toenails, but changes in the nail plate and nail bed can of course also occur on the hands.
In salon practice, we also encounter damage caused by unsuitable or incorrect product application, repeated mechanical stress, excessive filing or long-term unresolved lifting.
This is exactly why it is important not to confuse what we see with the cause of what we see.
Onycholysis is not automatically nail fungus
Onycholysis means separation of the nail plate from the nail bed.
The resulting space under the nail can look like an “air pocket”.
There can be many causes.
On toenails, long-term pressure or unsuitable footwear may play a role. On the hands, mechanical damage, trauma, inappropriate handling of the nails or damage related to nail enhancement may be involved.
Onycholysis can also accompany certain skin conditions or other health problems.
Onycholysis on its own is therefore not a diagnosis of nail fungus.
Onychomycosis is a fungal disease of the nail
Onychomycosis, on the other hand, is a fungal disease of the nail.
It may present with changes in color and structure, thickening, crumbling or separation of the nail plate from the nail bed.
This is why a nail affected by onychomycosis may initially look similar to onycholysis caused by a completely different factor.
This brings us back to the limits of the nail technician’s competence:
A nail technician may recognize and describe onycholysis. She should not decide from appearance alone whether the cause is a fungal infection.
If fungal infection is suspected, the correct approach is to recommend specialist assessment.
What about a green nail, often called a “greenie”?
Nail technicians encounter this problem relatively often, especially underneath enhancement material where lifting has occurred.
After removing the material, a green to green-brown discoloration may be visible on the natural nail and the first reaction is often:
“There is fungus under the gel.”
However, a green nail is usually not nail fungus.
The characteristic green discoloration is commonly associated with the bacterium Pseudomonas aeruginosa, which thrives in a moist environment.
The space created between lifted enhancement material and the natural nail can provide suitable conditions for it.
The green discoloration itself is not a “layer of fungus” or a bacterial deposit that can simply be filed away.
It is discoloration of the nail plate caused by pigments produced in connection with bacterial colonization.
Prevention is therefore also important.
Lifting is not only an aesthetic problem.
If a space develops between the product and the natural nail and moisture can enter it, it should not simply be covered with another layer of material.
The lifting should be properly removed and the condition of the natural nail checked.
How is nail fungus actually confirmed?
If onychomycosis is suspected, a dermatologist may arrange mycological testing.
Depending on the type of examination, material from under the nail or part of the affected nail plate may be collected.
The sample may then be examined microscopically, by culture or using another laboratory method.
Laboratory confirmation helps determine whether a fungal infection is actually present.
A nail technician can recognize a typical appearance and respond appropriately, but if the finding is extensive, unclear, painful or otherwise suspicious, the client should be referred for specialist examination.
Why is it important to refuse the service at the right time?
It is not only about one individual nail.
If an infectious disease is actually present, working on that nail may also create a risk of contamination of the work environment and spread of infectious material.
Even correctly sterilized and individually packaged tools are therefore not a reason to ignore a suspicious nail condition.
Salon hygiene includes the entire working area, tools, surfaces and the way the service is performed.
Sometimes the most professional action a nail technician can take is the one she does not perform.
Do not cover the nail. Do not try to “repair” the problem with product. Explain to the client what you can see and recommend the appropriate specialist.
After the health problem has been treated or ruled out, the client can return to the nail technician and together they can focus on recovery, protection and further care of the natural nail.
Where does ACESO fit in?
This is where an apparent contradiction may arise.
At DENATO, we offer the professional ACESO system for targeted care of problem nails, the nail bed and surrounding tissues.
We work with it, for example, in cases of onycholysis, hyperkeratosis, bacterial load or changes associated with a mycotic environment.
Does that mean a nail technician treats fungal disease with ACESO?
No.
ACESO is a professional supportive care system, not a medical device.
Its role is in targeted care of the nail, nail bed and surrounding tissues and in supporting an appropriate hygienic environment.
If the appearance or extent of the changes suggests a condition that requires diagnosis or medical treatment, specialist assessment comes first.
ACESO does not replace diagnosis or medical treatment.
And where does IBX fit in?
IBX and ACESO are not two systems for the same problem.
Each works in a different area.
IBX works within the natural nail plate.
We see its place in weakened, damaged, splitting and brittle natural nails, provided the condition is suitable for salon care.
ACESO focuses care more on the nail bed, the area beneath the nail and the surrounding tissues.
Sometimes IBX is the right choice, and in other situations ACESO may be more appropriate.
In certain cases, the two systems can be combined appropriately.
And sometimes neither should be the first step – a medical assessment should come first.
The ability to distinguish between these situations is more important than the product choice itself.
Why did we not immediately recommend ACESO or IBX to the customer?
You may wonder why we did not immediately recommend ACESO or IBX regeneration to the customer from the opening example.
Precisely because we offer these systems, we have to be even more responsible when recommending them.
Otherwise, it would be easy to create an oversimplified expectation:
“They have a product for problem nails, so it can be used whenever a nail does not look healthy.”
But that is not how it works.
If we are unsure of the cause of the nail change, it is not right to begin by selecting a product.
The correct order is:
- recognize that the nail condition is not normal,
- do not work over a suspicious condition,
- recommend specialist assessment when necessary,
- and only then consider regeneration or supportive salon care.
Sometimes IBX will be the right choice.
In other cases, ACESO.
Sometimes an appropriate combination of the two systems.
And sometimes the first step is medical examination and treatment.
We are not refusing to help. We simply do not want to promise something that neither DENATO nor a professional nail technician should provide.
This also protects professional nail technicians
ACESO and IBX naturally bring us questions that sit somewhere on the boundary between cosmetic care and a health problem.
The more professional information we provide, the more customers may begin to see us almost as an advisory service.
We see that as a sign of trust, but also as a reason to keep the limits of our competence very clear.
The same principle applies to professional nail technicians:
Recognize a suspicious condition – do not work over it – recommend specialist assessment – and only then address nail recovery.
This protects not only the client, but also the professional working with her nails.
Once a health problem has been ruled out, we return to salon care
If specialist assessment rules out a condition that requires medical treatment, or if the nail is suitable for professional salon care, we can return to what truly falls within the nail technician’s competence.
This includes care for:
- the natural nail plate,
- the nail bed,
- the surrounding tissues,
- mechanically damaged or weakened nails,
- and subsequent nail recovery.
Depending on the specific situation, IBX, ACESO or an appropriately selected combination of both systems may then have their place.
For more information about the differences between the two systems and when each one may be suitable, read our article IBX is not always enough. When to choose ACESO.
We want to gradually build a network of specialists we can refer clients to
At present, we do not yet have a public list of cooperating salons and specialists that we can automatically recommend to customers.
We also cannot, of course, share the contact details of our customers without their consent.
However, we would like to change this in the future.
Our goal is to gradually connect with competent specialists in different regions so that clients can be safely referred according to what they actually need.
The aim is not to create a list of “fungus salons”.
The purpose is to connect the client with the right professional – whether she needs dermatological assessment, professional foot care or subsequent professional care of the natural nail.
Summary: professionalism sometimes means knowing when not to work
Not every nail change is a fungal disease.
It is also not always possible to determine the cause of a nail change from appearance alone.
A nail technician can recognize changes in color, structure, onycholysis, damage or other unusual signs.
She does not need to – and should not – cross the boundary between observation and medical diagnosis.
If disease is suspected, specialist assessment comes first.
If it is later confirmed that the nail is suitable for salon care, the focus can return to what a professional nail technician does best – appropriately selected care of the natural nail plate, nail bed and surrounding tissues.
And that is when IBX, ACESO or a properly selected combination of both systems may have their place.
True professionalism is not only about knowing what to apply to a nail. It is just as important to know when not to apply anything yet.
