White flecks in your nails, also known as leukonychia, are a common occurrence and are usually not a cause for concern. They are most likely caused by minor trauma or injury to the nail, such as nail biting, picking at them, or even something more major like accidentally closing your finger in a car door. However, in some cases, they may indicate an underlying health condition such as vitamin or mineral deficiency, fungal infection, medication, liver disease, or even heart failure. While occasional white spots tied to specific injuries usually do not require medical attention, it is important to consult a healthcare professional if you notice frequent or widespread leukonychia, lines running through your nails, or other nail changes.

White flecks on nails, or leukonychia, can be caused by trauma to the nail from an injury
White flecks on nails, or leukonychia, are usually harmless and can result from minor nail trauma or injury. This can be caused by something as simple as tapping your fingers on a hard surface, a rough manicure, or even biting your nails. In these cases, the white spots are the result of damage to the nail plate or the area where the nail grows from, known as the matrix. This type of injury is common in children and is usually the cause of white spots on the nail.
When injured, the layers of keratin that make up your nails can crack or trap air between them, leading to white spots. These spots will grow out with the nail over time. To protect your nails from further trauma while you wait for the spots to diminish, keep them trimmed short, avoid over-filing or buffing, and try not to tap, pick, or bite at your nails. You can also try using nail strengtheners and cuticle oil to keep your nails strong.
In addition to physical trauma, chemical trauma from certain nail polishes and acrylic nails can also cause leukonychia. Leaving nail polish on for too long can prevent the nail from shedding cells normally, leading to dry, white areas. Allergies to nail products can also cause leukonychia, as can irritants such as nail polish remover, nail glue, or artificial nails.
While leukonychia is usually harmless, it can sometimes indicate an underlying health condition such as liver disease, anemia, or kidney disease. In rare cases, it can be a sign of a more serious medical issue like liver failure or heart failure. If you are concerned about the appearance of white spots on your nails, it is best to consult a healthcare professional.

They can also be caused by chemical trauma, such as certain nail polishes and acrylic nails
White flecks on nails, also known as leukonychia, are usually harmless but may indicate a medical condition. The most common cause of white spots on nails is injury or trauma, but they can also be caused by chemical trauma, such as certain nail polishes and acrylic nails.
Nail polishes and acrylic nails can cause chemical trauma to your nails, leading to white flecks. This can happen when you leave nail polish on for too long, not allowing the nail to shed cells normally. The chemicals used during manicures and pedicures can also be a factor, as well as the tools and polishes. In addition, an allergy to nail polish, gloss, hardener, or nail polish remover may cause white spots on your nails.
True leukonychia can be caused by irritants or allergens present in nail care products like nail polish and remover, nail glue, or artificial nails. These white spots originate from the nail matrix, where your nail grows, and appear on the nail plate. They do not disappear when pressure is applied.
To protect your nails from chemical trauma, it is recommended to keep them trimmed short and avoid over-filing or buffing. Using nail strengtheners and cuticle oil can also help keep your nails strong and healthy.

In rare cases, white spots on the nails can be a sign of a systemic illness or deficiency
White spots on the nails, known as leukonychia, are usually harmless and are often the result of a nail injury. However, in rare cases, they can indicate a more serious underlying health issue or deficiency.
Leukonychia can be a sign of vitamin or mineral deficiency, although this is extremely rare in people consuming a typical Western diet. Deficiencies that may cause leukonychia include zinc deficiency and iron deficiency anemia.
Systemic diseases, which affect the entire body, can also cause leukonychia. This is a rare occurrence, but white spots on the nails can sometimes indicate a more serious underlying problem, such as diabetes, heart failure, HIV, liver cirrhosis, or psoriasis.
Poisoning and medications can also lead to leukonychia. White spots may appear due to exposure to toxic heavy metals, such as arsenic and lead. Additionally, certain medications, such as those used for chemotherapy, bacterial infections, and urinary tract infections, including sulfa drugs, may cause leukonychia.
If you are concerned about persistent or worsening white spots on your nails, it is recommended to consult a doctor for a proper diagnosis and treatment.

White spots on the nails can be caused by fungal infections
White spots on the nails are usually the result of a nail injury called leukonychia. This occurs when there is damage to the nail matrix, the base of the fingernail that produces the nail plate. An injury to this area can cause white spots on your nail as it grows. However, because nails grow slowly, taking 6-9 months for a fingernail and 12-18 months for a toenail to regrow completely, you may not remember the injury that caused the spots.
True leukonychia occurs when the white spots form at the nail matrix, the beginning edge of the nail located under the skin just before the visible part of the nail. They appear in the hard part of your nail, called the nail plate. Apparent leukonychia happens when the white spots form on the skin beneath the nail (the nail bed), rather than on the nail itself. This type can be distinguished from true leukonychia because the spots fade when pressure is applied to the nail, and they do not move across the nail as the nail grows.
Pseudoleukonychia is caused by a fungus growing on the outside of the nail. This type causes the upper layers of the nail plate to become scaly. One common infection is onychomycosis, a fungal infection of the toenails. White spots tied to fungal infections can be treated with antifungal medications.
If you notice persistent or worsening white spots on your nails, it might be time to talk to a doctor. Doctors may refer to this condition as "punctate leukonychia". They will typically inspect the nails on your hands or feet and may perform tests such as mycology (studying nail clippings under a microscope), nail biopsy, or blood tests to identify any underlying issues.

They can also be caused by allergies to nail products
White spots on your nails, known as leukonychia, are usually harmless and are commonly caused by injuries to the nail plate or nail matrix. However, in some cases, they can be caused by allergies to nail products, such as nail polish, nail gloss, nail hardener, nail polish remover, or even artificial nails.
If you suspect that your white nail flecks are due to an allergic reaction to nail products, it is recommended to stop using the product you believe is causing the issue. Your immune system may interpret these products as allergens, leading to the formation of white spots. This reaction can occur with frequent use of irritant or allergenic grooming products. Therefore, it is advisable to limit the application of such products and opt for gentle nail care practices.
Allergic reactions to nail products can cause true leukonychia, which occurs when the white spots form in the area where the nail starts to grow (nail matrix) and appear in the hard part of the nail (nail plate). It is important to distinguish true leukonychia from apparent leukonychia, where the nail bed under the nail is affected, causing the colour of the nail plate to change. With true leukonychia, the white spots remain unaffected when pressure is applied, and they will grow out as the nail does.
If you continue to experience symptoms of an allergic reaction after discontinuing the use of certain nail products, it is recommended to consult a doctor. They may advise you to take oral antifungal medication or prescribe a topical antifungal treatment. Additionally, maintaining proper nail care, such as moisturising your nails and keeping them trimmed, can help prevent and manage white spots caused by allergies.
While white nail flecks due to allergies are typically not a cause for serious concern, it is always a good idea to prioritise nail health and take appropriate measures to identify and address any potential allergens.

Frequently asked questions
White spots on your nails, also known as leukonychia, are usually harmless but may indicate a medical condition. The most common cause of white spots on the nail is injury, which can be prevented with proper nail care. Other possible causes are allergies to nail products, fungal infections, vitamin deficiencies, and heavy metal poisoning.
There are three major types of leukonychia: true leukonychia, apparent leukonychia, and pseudoleukonychia. True leukonychia occurs when the white spots on your nails form at the nail matrix. Apparent leukonychia happens when the white spots form on the skin beneath the nail, rather than on the nail itself. Pseudoleukonychia is caused by a fungus growing on the outside of the nail.
If you have isolated white spots on your nails, it is likely caused by nail injury and will usually grow out with the nail. However, if you have white lines along your nail or your entire nail looks white, it is recommended to see a healthcare professional as it may indicate an underlying medical condition.
