Fingernails can provide clues about a person's health, and changes in their appearance may indicate an underlying disease. While not all changes to the nail are bad, some nail abnormalities can be symptoms of serious conditions. One common change is the appearance of white tips, which can be caused by a variety of factors, including trauma, anemia, dietary deficiencies, and environmental factors.

Fingernail anatomy
The nail is a protective plate found at the tip of the fingers and toes of all primates. It is made of a tough, rigid protein called alpha-keratin, which is also found in the claws, hooves, and horns of vertebrates. The nail has several components, each serving a specific function.
The nail plate, or the top part of the nail, is the hardest and most visible part of the nail. It is made of keratin, a protein also present in the hair and skin. The nail plate is transparent, and the colour we see is due to the colours underneath it. The nail plate is supported by several soft tissue structures, including the nail matrix and the nail bed.
The nail matrix is the structure at the base of the nail plate from which new nail cells grow. It is also known as the matrix unguis, keratogenous membrane, or onychostroma. The lunula is the half-moon-shaped visible part of the nail matrix, although it may not be visible on every nail. The nail matrix contains nerves, lymph, and blood vessels, and produces cells that harden as they move outward to form the nail plate. The width and thickness of the nail plate are determined by the size and shape of the nail matrix.
The nail bed is the soft tissue beneath the nail plate that contains nerves, lymph, and blood vessels. The nail folds are soft tissue structures that protect the edges of the nail plate and the nail matrix from trauma and ultraviolet radiation. The mantle is the skin that covers the nail matrix and the base of the nail plate.
Healthy fingernails are smooth and have different colours as they grow out. They are actually transparent, and the colour we see is due to the underlying structures. The nails help strengthen the fingertips, enhance fine motor skills, and improve tactile sensation. They receive blood supply from the superficial palmar arch, which branches into the common and proper digital arteries, supplying blood to the nail fold, nail matrix, and the rest of the nail unit.

Environmental factors
Fingernail changes, including white discolouration, can be caused by environmental factors, injuries, or medical conditions. While some nail abnormalities are harmless, others may indicate an underlying health condition. If you are concerned about the appearance of your nails, it is recommended to consult a doctor or dermatologist.
White fingernails can be caused by various environmental factors, including:
- Chemical Exposure: Exposure to chemicals such as detergents, nail polish, nail polish remover, and alcohol-based hand sanitizers can lead to dry, brittle, or discoloured nails. To minimize the impact of these chemicals, it is advisable to wear gloves when using chemical cleaners and to opt for nail polish removers that do not contain acetone.
- Weather: Changes in weather conditions can affect nail health. Dry, cold weather, in particular, can contribute to nail dryness, which may result in nail discolouration.
- Frequent Handwashing: Washing your hands frequently can strip your nails of their natural oils, leading to dryness and potential discolouration. While good hand hygiene is important, avoiding excessive handwashing can help maintain nail health.
- Nail Care Practices: Certain nail care habits can contribute to nail discolouration. For example, excessive use of nail polish can hinder nail health. Additionally, aggressive manicuring, such as frequent nail biting, picking, or the use of false nails, can lead to nail trauma and subsequent discolouration. Allowing your nails to breathe by occasionally avoiding nail polish and minimizing these practices can help prevent white nails.
- Vitamin and Mineral Deficiencies: Low levels of B vitamins, calcium, or iron can cause nail discolouration. Ensuring adequate nutrient intake through a balanced diet can promote nail health and prevent white spots on your nails.

Health indicators
Fingernails are made of the protein keratin and flattened cells. They are usually transparent, but can change colour due to various environmental factors, injuries, or medical conditions. While not all changes to fingernails are a cause for concern, some nail discolouration can indicate underlying health issues.
White nail tips are usually a sign of healthy nails. As nails grow out beyond the nail bed, they tend to turn white because they are dry. However, if the nail is mostly white with darker rims, this could indicate liver problems such as hepatitis. This condition, known as Terry's nails, can also be attributed to ageing. Whole nail whitening is generally associated with kidney problems, specifically protein deficiency in the body. When whitening is accompanied by thickened nail plates, it could be a sign of a fungal infection.
White spots on the nails are usually harmless and are caused by injuries such as striking the fingertip. However, they could also be indicative of previous trauma to the nail plate, dietary deficiencies, or poisoning. Nails that are thin and brittle could be a sign of a thyroid disorder. Pale nails may indicate illnesses such as anaemia, an iron deficiency that can be corrected through diet and supplements. Other symptoms of anaemia include fatigue, dizziness, and constipation.
Horizontal lines or grooves that run across the nail indicate slowed or stopped nail growth, which could be caused by high fever, stress, damage to the cuticle, or certain medications. In some cases, they may also be a marker of uncontrolled diabetes or cancer treatment. Curved or "clubbed" nails may be associated with lung disease, inflammatory bowel disease, cardiovascular disease, or liver disease.

Trauma
White spots on nails, also known as leukonychia, are a common occurrence and usually do not indicate a serious problem. They are often the result of trauma or injury to the nail plate or nail matrix, which is the base of the fingernail that produces the nail plate. This can happen when you accidentally close your finger in a car door, strike your finger with a hammer, or even from a rough manicure. In addition, nail biting, knocks, bangs, and wearing tight shoes can also cause leukonychia.
True leukonychia is when the discolouration is due to abnormal nail plate keratinisation. The white nail will not be hidden by pressure application of the nail plate to the bed. It originates in the matrix of the nail, the part responsible for nail production, and can be caused by injury to this area. Apparent leukonychia, on the other hand, is secondary to disease of the nail bed. This appears as white spots on the skin beneath the nail and disappears with pressure application on the nail.
Punctate leukonychia occurs after nail biting, manicuring, knocks, bangs, and tight footwear use. There is no specific treatment for trauma-induced leukonychia, but it can be prevented by avoiding contact with irritating substances and wearing protective equipment. Leukonychia due to minor trauma may resolve on its own over a few months as the nail grows out. Fingernails typically take 6 months or more to grow out fully, while toenails can take up to 18 months.
If you are concerned about the appearance of your nails or if the white spots are accompanied by other symptoms, it is recommended to consult a doctor or dermatologist for a proper diagnosis and treatment plan.

Treatments
White nails, or leukonychia, can be caused by several factors, including injury, trauma, anemia, dietary deficiencies, liver or kidney disease, poisoning, or even an allergic reaction. While it may be harmless in most cases, it could also indicate a more serious underlying condition. Therefore, it is important to consult a doctor or dermatologist for a proper diagnosis and treatment plan.
If your white nails are caused by an injury, such as accidentally closing your finger in a door or nail biting, you may not need any specific treatment. The white spots will usually grow out over time, and you can simply trim them with nail clippers or scissors once they reach the end of your nail. This can take anywhere from 6 to 18 months for fingernails and even longer for toenails. In the meantime, you can use nail polish to cover up the spots if desired.
However, if your white nails are not due to an injury, it is important to consult a doctor. They may recommend a variety of tests, including blood tests, to evaluate your overall health and check for any underlying conditions. Treatment will depend on the specific cause identified. For example, if a fungal infection is causing your white nails, your doctor may prescribe antifungal medications.
Additionally, maintaining a balanced diet and adequate vitamin intake can help prevent mineral deficiencies, which are a common cause of white nails. Ensuring proper nutrition may help prevent or improve the condition.
To prevent further damage to your nails, you can take protective measures such as wearing gloves during activities that may damage your nails and choosing comfortable and protective shoes. Keeping your nails trimmed short and moisturized can also help. It is important to be cautious when using chemicals or other products on your nails, as they may contribute to the issue.
If you notice any other symptoms accompanying your white nails, such as weakness, fatigue, blurred vision, or shortness of breath, it is crucial to seek medical advice promptly.
