A loose nail can be a troubling symptom, especially if you don't know what caused it. Typically, a loose nail is a gradual process that only impacts part of the nail. However, in some cases, like nail trauma, the entire nail can come loose rather quickly. There are several reasons why your nail might be coming loose from your finger, including a fungal infection, injury, or an underlying health condition such as psoriasis, hyperthyroidism, or iron deficiency.

What You'll Learn
Nail trauma
Trauma to the nail can cause nail loosening and, in some cases, even complete nail loss. Nail trauma can occur due to various reasons, including dropping something heavy on the nail, crushing the nail, or slamming a door on the nail. Bleeding beneath the nail can also cause enough pressure for the nail to loosen and, in some cases, fall off. Repeated trauma, such as repeatedly tapping the nails for a long time, can also lead to nail separation from the skin.
The treatment for nail trauma and onycholysis will depend on the underlying cause. In the case of onycholysis, the first step is to identify the cause of nail lifting and address it. General measures to support nail health include keeping the nails trimmed and short, avoiding activities that can cause nail injuries, and steering clear of irritants and nail products. In the case of nail trauma, if there is bleeding, it is advised to reach out to a doctor.
The recovery time for onycholysis depends on nail growth, which is usually quite slow. Fingernails can take around 4 to 6 months to grow to full size, while toenails may take up to 12 to 18 months. With onycholysis, the detached portion of the nail will not reattach, and the focus will be on new nail growth and maintaining the attachment to the nail bed.

Fungal infections
Onycholysis is the medical term for nail separation, which occurs when a nail separates from the nail bed (the skin on which the nail rests). It is usually painless and affects only one nail. However, it can last for several months or over a year. Onycholysis can be caused by various factors, including fungal infections, which are the focus of this discussion.
Fungal nail infections are typically more prevalent in toenails, but they can also occur in fingernails. They usually start at the edge of the nail. You are more susceptible to these infections if your feet are often warm and damp, or if you wear tight-fitting shoes for extended periods, resulting in sweaty feet.
To treat fungal nail infections, oral and topical antifungal medications are available. Oral medications include antifungal tablets or liquid medicines prescribed by a healthcare provider. Topical treatments come in the form of creams, ointments, or gels that are applied directly to the affected nails. It is crucial to complete the full course of treatment to prevent a recurrence and ensure the infection's eradication.
In summary, fungal infections can cause nail separation or onycholysis. While this condition is generally painless, it can last for an extended period. Seeking medical advice and adhering to the prescribed treatment plan are essential steps in managing and resolving fungal nail infections and their associated nail separation.

Psoriasis
Onycholysis, or nail separation, can be caused by a variety of factors, including injury, fungus, or psoriasis. If you notice that your nail is lifting or peeling away from the nail bed, it is likely onycholysis. While this condition is generally painless, it can be unsightly and may indicate an underlying health issue.
Nail psoriasis is an autoimmune disease that affects the nails on both fingers and toes, causing discoloration, pitting, crumbling, and changes in nail structure. It is often accompanied by a psoriatic rash on other parts of the body. While there is no cure for nail psoriasis, various treatments can help alleviate symptoms, including corticosteroid injections or creams, oral medications, and natural remedies such as capsaicin, Dead Sea salt soaks, and turmeric.
If you suspect that your nail separation is caused by nail psoriasis, it is important to consult a dermatologist for diagnosis and treatment. They may recommend a treatment plan that includes one or a combination of the following:
- Corticosteroid injections: Injections of corticosteroids or other psoriasis medications can effectively treat nail buildup, ridges, thickening, and separation. These injections are typically administered directly into or near the affected nails every 4 to 6 weeks.
- Laser treatments: While lasers have been studied as a potential treatment for nail psoriasis, more research is needed before they can be recommended.
- Systemic treatment: If you have severe psoriasis affecting both your skin and nails, your dermatologist may prescribe medication to treat both areas simultaneously.
- Topical treatments: Your healthcare provider may prescribe a corticosteroid cream, ointment, or nail polish to apply to the affected area. However, it can be challenging to ensure that these treatments reach the nail bed and the area where the nail begins to grow.
- Oral medications: In more severe cases, your healthcare provider may prescribe oral medications such as methotrexate, cyclosporine, or apremilast.
It is worth noting that nail changes, including separation, can also be a sign of psoriatic arthritis (PsA). Therefore, if you notice any changes in your nails, it is essential to consult a dermatologist for diagnosis and appropriate treatment.

Hyperthyroidism
Nail separation, or onycholysis, can be caused by a number of factors, including injury, fungus, or psoriasis. While onycholysis is generally not painful, it can be a symptom of an underlying health condition, such as thyroid disease.
Thyroid disease, including hyperthyroidism, can cause a variety of symptoms, including nail changes. These nail changes may include thick, dry, and brittle nails with visible ridges, or soft, shiny nails that crumble easily. Nails may also grow more slowly or quickly, peel, crumble, or break easily, and lift up from the nail bed. Curved nails with swollen fingertips and thickening skin above the nail are also common indicators of thyroid disease.
If you are experiencing nail separation or other nail changes, it is important to consult a healthcare professional, such as a dermatologist, to determine the underlying cause. They may recommend a blood test to check for thyroid disease or other potential causes. Treating the underlying condition will help resolve the nail separation, and in the case of hyperthyroidism, early treatment can prevent complications such as an injury that refuses to heal or an irregular heartbeat.

Iron deficiency
Onycholysis, or nail separation, is a common condition where the nail separates from the nail bed. It is usually painless and affects only one nail. While onycholysis can be caused by several factors, including injury, fungus, or psoriasis, it can also be a sign of iron deficiency.
The treatment for onycholysis caused by iron deficiency aims to address the underlying issue. Increasing iron intake through dietary changes or supplements is often recommended. Iron-rich foods include meat, seafood, beans, lentils, dark chocolate, fortified foods, iron-rich fruits (such as dates, figs, prunes, and raisins), leafy greens (such as spinach or kale), and nuts and seeds.
It is important to consult a healthcare professional to determine the cause of onycholysis and receive appropriate treatment. In the case of iron deficiency, they may recommend dietary changes or supplements to correct and prevent spoon nails and associated nail separation. Additionally, keeping nails trimmed and avoiding activities that may harm them can help manage onycholysis while treating the underlying cause.
