A nail that is separating from its nail bed should be assessed when the cause is not obvious. Arrange medical care sooner if the surrounding skin is red, swollen, sore or warm; if you notice a new or changing dark streak or other suspicious nail change; or, after an injury, if pain is severe, movement is limited, bleeding covers much of the nail, or the nail is black or purple.
The medical term for nail lifting is onycholysis. The detached portion cannot be glued back to the nail bed, so treatment focuses on protecting the area, helping new nail grow normally and finding the underlying cause.
What a lifting nail means
Onycholysis occurs when the nail plate separates from the nail bed beneath it. The separated area often looks white, pale or opaque because air has entered the space. That appearance describes the separation, not its cause. Color alone cannot tell you whether the problem is an injury, infection, psoriasis or another condition.
The American Academy of Dermatology Association (AAD) advises having a dermatologist examine any nail that is lifting. Examination matters because some causes need specific treatment, and correct care can help the newly growing nail remain attached. DermNet New Zealand also lists medication or systemic factors and, less commonly, tumours among possible causes.

The part that has already detached does not reattach. A product, adhesive or home remedy cannot make it adhere again. The goal is to prevent further trauma while the nail grows forward and to treat whatever caused the separation.
When a lifting nail needs urgent attention
Use the pattern and severity of symptoms to choose the appropriate route. The following table separates unexplained changes, possible infection, suspicious pigment and acute injury.
| Situation | What to do | Why it matters |
|---|---|---|
| Unexplained lifting, shape change or color change | Arrange an appointment with a clinician; a dermatologist is appropriate where available. | The cause cannot be established reliably from appearance alone, and the AAD recommends examination of a lifting nail. |
| Red, swollen, sore or warm skin around the nail | Seek medical advice promptly. | This pattern can indicate infection or an inflamed nail fold. |
| New or changing dark streak, dark skin beside the nail, a split nail, or a bump beneath it | Arrange dermatology assessment. | The nail unit can be affected by melanoma and other growths. These signs are not a diagnosis, but they should not be ignored. |
| After an injury: inability to bend the finger or toe, blood covering more than half the nail, black or purple nail, or particularly severe pain | Seek a dermatologist or emergency medical care. | These are the AAD’s warning signs for a potentially significant injured nail. |
The injury criteria above are guidance for injured nails, not a complete emergency rule for every medical situation. If you feel seriously unwell, have uncontrolled bleeding or have another immediate concern, use your local emergency service.

A nail can lift after a knock, repeated pressure, wet work or another mechanical injury. It can also separate because of a fungal infection, psoriasis or another inflammatory skin disease. Some medicines and systemic illnesses may contribute, and DermNet includes tumours in the list of possible causes. Several conditions can look alike, so starting treatment based only on a white area or a change in color can delay the right diagnosis.

What a clinician may need to know
- When you first noticed the separation and whether it is spreading.
- Any recent impact, pinching, manicure, pedicure, repetitive pressure or chemical exposure.
- Whether other fingernails or toenails are changing.
- Previous psoriasis, eczema, fungal nail disease or other skin problems.
- Medicines, chronic illnesses and whether you have diabetes or a weakened immune system.
Bring a list of medicines and, if the appearance has changed over time, dated photographs. Do not assume that a dark or white color identifies fungus. A clinician may inspect the nail and surrounding skin and decide whether testing or targeted treatment is needed.
Signs that the surrounding skin may be infected
Infection is more concerning when the skin around the nail becomes sore, red, swollen and warm. The NHS describes this combination as a possible infection or an ingrown-nail problem. Contact a clinician rather than trying to dig under the nail or applying a random antibiotic or antifungal product.
For suspected fungal nail infection, the NHS recommends medical review when the infection is severe, spreading to other nails or not responding to treatment. Review is also important if you have diabetes or a weakened immune system, because complications and treatment choices can differ. A lifted nail does not prove that fungus is present; confirmation may be needed before treatment.

Arrange dermatology review for a new or changing dark streak, darkening of the skin next to the nail, a split nail, or a bump or nodule under the nail. The AAD notes that nail lifting can occur among the changes seen with nail melanoma guidance, although many non-cancerous conditions can cause the same features.

Do not wait for pain. Nail melanoma may present as a changing pigment or structural alteration rather than an acute injury. Photograph the nail in consistent lighting so a clinician can compare progression, but do not use photographs to rule out a serious condition.
What to do after a minor nail injury
If the lifting clearly followed a minor injury and none of the severe warning signs is present, protect the area while arranging care if the cause or extent is uncertain. The AAD recommends the following limited first aid:
- Trim only the disconnected piece. If part of the nail is hanging off, gently clip the portion that is no longer attached to skin. Do not pull on a section that remains connected.
- Clean gently. Wash the area with soap and water. Avoid scraping beneath the nail.
- Control bleeding first. If it is still bleeding, use gentle pressure with clean material. Once bleeding has stopped, apply petroleum jelly.
- Cover the injury. Place gauze or a bandage over the area to reduce friction and contamination.
- Keep adhesive off the injured nail. Put sticky products on the surrounding skin rather than directly on the damaged nail plate.
The NHS specifically advises against cleaning under nails with sharp objects. Probing can injure the nail bed, drive debris deeper or worsen separation. This first-aid sequence protects a minor traumatic injury; it does not diagnose unexplained onycholysis or treat an infection.

Known minor trauma without red flags
Protect the nail as described above and monitor it. Arrange a routine clinician or dermatology appointment if the separation continues, the cause is not completely clear, or the new nail does not appear to be growing normally. Escalate sooner if pain, swelling, warmth, drainage or discoloration develops.

Possible infection or higher-risk health condition
Seek medical advice when the surrounding skin is sore, red, swollen or warm. Do not delay review of a suspected fungal infection if it is severe, spreading, persistent despite treatment, or occurring with diabetes or immune suppression.
Suspicious pigment or structure
Request dermatology assessment for a new or changing dark streak, adjacent dark skin, a split nail or an under-nail lump. These changes have many possible explanations, but visual inspection at home cannot safely exclude melanoma.
Severe acute injury
Use emergency medical care or urgent dermatology care when you cannot bend the finger or toe, blood covers more than half the nail, the nail is black or purple, or the injury is particularly painful. These signs can accompany deeper damage that needs professional assessment.
What happens to the detached nail
The detached segment remains separated until it is clipped away or grows out with the nail. It cannot be reattached to the nail bed. New growth comes from the nail-producing area at the base, and the practical aim is to keep that new nail attached as it advances.
Recovery depends on the cause, the amount of nail-bed injury and whether infection or inflammation is present. Keep follow-up appointments if a clinician recommends them, because a change in appearance alone does not show that the underlying problem has resolved.
Common mistakes to avoid
- Do not diagnose from color alone. White, yellow, brown, black or opaque areas can have different causes.
- Do not start antifungal treatment without evidence of fungal infection. It may be ineffective and can postpone evaluation of another condition.
- Do not glue or tape the detached portion back down. The separated section will not reattach, and adhesives can irritate injured skin.
- Do not pull off attached nail. Trim only the section that is completely disconnected from skin.
- Do not probe under the nail with sharp tools. This can cause additional nail-bed damage.
- Do not ignore progressive pigment or a new lump. A painless change still merits assessment.
A practical decision checklist
Use this checklist when deciding what to do today:
- Is the cause unexplained? Arrange a clinician or dermatology appointment.
- Is the skin around the nail sore, red, swollen or warm? Seek medical advice for possible infection.
- Is there a new or changing dark streak, adjacent dark skin, a split nail or a bump? Request dermatology review.
- Did an injury cause the lifting? For a minor injury, trim only disconnected nail, wash with soap and water, apply petroleum jelly after bleeding stops and cover it.
- Can you not bend the finger or toe, does blood cover more than half the nail, is it black or purple, or is pain particularly severe? Seek emergency medical care or urgent dermatology care.
The NHS route described here is UK-specific and refers to a general practitioner. Outside the UK, use your local primary-care, urgent-care or dermatology service. No single prevalence figure establishes how common onycholysis is across all causes, so the safest decision is based on the individual signs above rather than on a percentage.
