Warning signs
| Sign | Action |
|---|---|
| Green discolouration | See a doctor |
| White or yellow patches spreading | See a doctor |
| Nail separating from the bed | See a doctor |
| Thickening or crumbling | See a doctor |
| Pain, throbbing or swelling | See a doctor promptly |
| Pus or discharge | See a doctor promptly |
| Foul odour | See a doctor |
Do not try to identify this from photographs online. Several different conditions look similar, they have different causes, and they are treated differently. Getting it wrong wastes months, and nails are slow enough already.
What not to do
| Do not | Why |
|---|---|
| Cover it with another set | Traps moisture and delays diagnosis |
| Apply polish over it | Same problem, smaller scale |
| Use a home remedy you read about | Delays proper treatment |
| Wait to see if it clears | Some conditions progress |
| File or scrape at it | Can spread the problem |
Covering a problem nail is the single worst response, and it is extremely common. The impulse is understandable — it looks bad and you want it hidden — but a sealed, damp nail is exactly the environment that made it worse in the first place.
How these problems usually develop
| Mechanism | Note |
|---|---|
| Moisture trapped under lifted product | The most common route by far |
| Trauma during application or removal | Aggressive filing, or prying a set off |
| Contaminated implements | Sanitation — ask how tools are handled |
| Applying over an already compromised nail | Seals in whatever was there |
When product lifts, water gets underneath and stays there. That is why picking at a lifted edge matters, and why lifting should be repaired promptly rather than ignored until the next appointment.
Prevention
- 1Get lifting repaired promptly. Do not wait, and do not pick at it.
- 2Ask how implements are sanitised. It is a reasonable question and a good salon answers it easily.
- 3Do not apply over damaged or lifting nails. Have them removed and assessed first.
- 4Take a break if nails are already compromised.
- 5Dry hands thoroughly, especially under the free edge.
- 6Do not share nail tools, including at home.
What to expect at the appointment
People delay seeing a doctor partly because they do not know what will happen. It is usually straightforward.
- Expect the product to be removed before anything can be assessed properly.
- Expect a possible sample to identify what is actually there — several conditions look alike.
- Expect a slow timeline. Nail conditions often take months to resolve because nails grow slowly, not because treatment is failing.
- Expect to be told to leave it uncovered for a while. That part is not negotiable.
After treatment
If a doctor diagnoses and treats a nail condition, wait until they clear you before returning to enhancements. Reapplying early risks recurrence, and you will have spent months for nothing.
When you do go back, tell the technician what happened. A good salon would rather know, both so they can be gentle with prep and so they can keep an eye on how that nail is behaving.
Frequently asked questions
Q.Is green under my nail an infection?
Discolouration under a nail can indicate several different conditions. See a doctor for a diagnosis rather than identifying it online.
Q.Can I just put another set over it?
No. That traps moisture, delays diagnosis, and is the most common wrong response.
Q.Will it clear on its own?
Some conditions do not, and some progress. Get it assessed rather than waiting.
Q.How long does treatment take?
It depends on the diagnosis. Nail conditions often take months simply because nails grow slowly.
Q.Can I get acrylics again afterwards?
Once your doctor clears you. Going back early risks recurrence.
