White stripes on the fingernail, also known as leukonychia, can be caused by various factors, including injury to the nail matrix or bed, mineral deficiency, or underlying health conditions. While they are usually not indicative of a severe issue, white lines on the nails can sometimes signify a more serious medical condition.

White stripes on nails, or leukonychia, can be caused by injury to the base of the nail
There are two types of leukonychia: true leukonychia and apparent leukonychia. True leukonychia is the most common form, where small white spots appear on the nails. This can be caused by nail-biting or picking in young children and nail biters. It can also be caused by parakeratosis or air trapped between the cells. In most cases, when white spots appear on one or a few nails, it is due to an injury to the base of the nail. These spots disappear after around eight months, which is the time it takes for nails to regrow completely.
Apparent leukonychia is caused by changes in the nail bed that are visible through the nail plate. This type of leukonychia involves a problem with the nail bed under the nail, not the nail itself. It is commonly caused by minor injuries, such as nail biting, or may occur while the nail is growing. Apparent leukonychia is harmless and unrelated to any known nutritional or physiological deficiency. The marks caused by injury will disappear as the nail grows outwards.
Leukonychia can also be classified by its distribution or how it develops. Striate leukonychia, or Mees' lines, are horizontal bands that are parallel to the base of the nail. They are commonly caused by physical injury or disruption of the nail matrix, such as excessive biting or tapping of the nails, or trauma from accidents involving doors or windows. It may also be caused by heavy metal poisoning, cirrhosis of the liver, or chemotherapy. Total leukonychia follows a more serious injury, often with detachment of the nail plate from the nail bed and alteration to the nail contour.
While white spots on the nails are common and rarely indicate a serious medical issue, they can sometimes be a symptom of an underlying health problem. Mees' lines, for example, are associated with acute systemic stress, acute renal failure, heart failure, ulcerative colitis, breast cancer, carbon monoxide poisoning, and exposure to toxic metals. Therefore, it is important to talk to a healthcare provider if you notice persistent white stripes or bands on your nails to determine the underlying cause and receive appropriate treatment.

Mees' lines are white stripes that can be a symptom of arsenic poisoning
White stripes on fingernails, known as Mees lines, can be a symptom of arsenic poisoning. They are smooth, horizontal white bands that span the width of the nail plate, usually affecting all fingernails. They are typically non-painful and are not bumps or ridges. Mees lines are often a symptom of an underlying health problem, and they have historically been associated with arsenic poisoning.
Mees lines were first described by E.S. Reynolds in 1901, again in 1904 by C.J. Aldrich, and ultimately credited to R.A. Mees in 1919. All three physicians described the physical finding in relation to arsenic poisoning. Mees lines are thought to occur due to abnormal keratinization of the nail plate following an injury to the nail matrix. They usually appear a couple of weeks after exposure to arsenic. Nails grow about 0.1 millimetres per day, so the time since exposure can be estimated by measuring from the cuticle to the Mees line.
Mees lines may be mistaken for Muehrcke lines or injury to the nail. They can also be caused by other types of poisoning, such as from thallium, selenium, or fluorine, as well as severe infections, heart disease, and malignancy. Additionally, they have been associated with acute systemic stress, altitude sickness, carbon monoxide poisoning, chemotherapy, heart failure, kidney failure, and Hodgkin lymphoma.
If you notice white lines on your fingernails or toenails, it is important to talk to a healthcare provider as they can be a sign of a serious underlying health condition. A healthcare provider can evaluate you for poisoning or disease and recommend appropriate treatment.

Kidney failure can cause half-white, half-brown fingernails
White lines or bands that appear on the fingernails or toenails are known as Mees' lines. They are often a symptom of an underlying health problem and can be a sign of a serious illness. Historically, Mees' lines have been associated with arsenic or other heavy metal poisoning. However, they may also be a sign of kidney failure.
Mees' lines are smooth, light lines that appear across the nails, usually running the entire width of the nail. They start at the bottom, closest to the cuticles, and then move toward the top of the nail over time. While they can appear on only one nail, they often affect all nails simultaneously.
In the context of kidney disease, Mees' lines are known as Muehrcke's lines or Muehrcke's nails. They are characterised by white bands running parallel to the base of the fingernail and are indicative of kidney dysfunction. These bands develop due to low levels of albumin, a protein in the blood, which is common in individuals with impaired kidney function.
Kidney disease can lead to malnutrition and imbalances in calcium, phosphorus, and other minerals, affecting nail health. This can result in weak, brittle nails that break more easily or feel softer than usual. In some cases, nails may become thin, peel, or split. Additionally, kidney disease can cause changes in nail colour, texture, and shape. Nails may develop concave or spoon-shaped dents, a yellow overcoat, or an unnatural white and red-brown coloration that divides the nail in half, known as Lindsay's nails or half-and-half nails.
Therefore, the appearance of half-white, half-brown fingernails, or Lindsay's nails, can be indicative of kidney failure. This colour change results from increased blood vessels under the nail bed, coupled with changes in the production of keratin, the protein responsible for nail growth. It is important to consult a healthcare provider if you notice any significant or persistent changes in your nails, especially if you have been diagnosed with kidney disease or are at risk for it.

White spots on nails are usually harmless and disappear as the nail grows out
White spots on nails, also known as leukonychia, are usually harmless and often disappear as the nail grows out. They are a common condition and can be caused by minor nail trauma, such as bumping your nails against a hard surface or biting them. In these cases, the white spots will eventually grow out, and you can simply trim them off with nail clippers or scissors. This process can take up to six to nine months for fingernails and 12 to 18 months for toenails.
There are three types of leukonychia: true leukonychia, apparent leukonychia, and pseudoleukonychia. True leukonychia originates from the nail matrix, the area where the nail starts to grow, and appears in the hard part of the nail (nail plate). These spots do not disappear with pressure. Apparent leukonychia, on the other hand, occurs in the skin beneath the nail (nail bed) and is caused by abnormal nail bed vasculature. The whiteness in this type disappears with pressure. Pseudoleukonychia appears as flaking on top of the nail and is often caused by fungal infections or outside organisms like fungi.
While rare, white spots on nails can sometimes indicate a more serious underlying health condition. Mees' lines, for example, are white lines or bands that appear across the nails and are associated with acute systemic stress, poisoning, or disease. They have been linked to conditions such as acute renal failure, heart failure, ulcerative colitis, breast cancer, and exposure to toxic metals. Therefore, if white spots on your nails are accompanied by other severe symptoms or do not grow out and disappear, it is recommended to consult a healthcare professional for further evaluation and diagnosis.
Additionally, skin conditions like alopecia areata, lichen planus, and atopic dermatitis can also cause white spots on the nails. Certain medications, allergies, and fungal infections can also be contributing factors. In these cases, antifungal treatments or discontinuing the use of certain products may be recommended.
Overall, while white spots on nails are typically harmless and will grow out over time, it is always a good idea to monitor any changes in your body and seek medical advice if you have any concerns or if the spots persist.

Hailey-Hailey disease is a rare inherited disease that causes white stripes on the nails
White stripes on the nails, or Mees' lines, can be indicative of a serious underlying health condition. These lines are usually a symptom of poisoning, such as from arsenic or other heavy metals, or disease. They can also be caused by injury to the nail or nail bed.
In some cases, white stripes on the nails can be a sign of Hailey-Hailey disease, a rare inherited disease. Hailey-Hailey disease, also known as familial benign pemphigus, is a genetic disorder caused by a mutation in the ATP2C1 gene. This gene is responsible for creating a protein that is essential for maintaining healthy skin. The disease is characterised by blisters and erosions that most often affect the neck, armpits, skin folds, and genitals. The symptoms of Hailey-Hailey disease occur due to the failure of skin cells to stick together, resulting in the breakdown of affected skin layers.
The symptoms of Hailey-Hailey disease usually appear after puberty, typically in the third or fourth decade of life, but they can develop at any age. The severity of the disease varies from person to person, even among family members. The disease is often relapsing and remitting, meaning the lesions may come and go and usually heal without scarring. However, sunlight, heat, sweating, and friction can aggravate the condition.
Patients with Hailey-Hailey disease exhibit nails with multiple parallel longitudinal white stripes of variable width originating in the lunula and most prominent on the thumbs. Additionally, these patients experience recurrent vesicular eruptions in flexural skin areas, such as the groin, axilla, neck, and periumbilical area. The presence of nail findings in Hailey-Hailey disease can aid in a more rapid diagnosis and treatment.
