White spots on nails: what are the possible causes?

White spots can have various origins. They can result from shock, fungal infection, an allergy, or be a symptom of another disease. In this guide, you’ll learn all the possible causes of white spots on your nails.

Microtrauma to the nail matrix

Trauma to the nail is the most common cause of leukonychia. Various causes can cause these microtraumas, such as shock, pinching, or a minor injury. They can also be caused by rough manicures: the back-and-forth motions of the file tend to damage the nail, as does pushing back the cuticles too roughly or biting your nails. On the feet, trauma can come from overly long nails that hit the end of your shoe when walking.

To avoid these problems, remember to keep your toenails short. Choose to use gentle nail files, and always file your nails in the same direction. Choose quality manicure and pedicure sets, whether you prefer gel nails, acrylic nails, semi-permanent nail polish, or a French manicure.

An allergy to products in contact with nails

White nails may be a sign of an allergy to a product in contact with the nails. The first thing to think about is manicure products: nail polish, nail polish remover, false nails, gel nail kits, but cleaning products or other chemicals may also be the cause.

In this case, avoiding the allergen will allow the condition to return to normal. In addition, when choosing nail products, you should consider more trustworthy big brands, such as Maryton Nail Supplies.

Mycosis, a common cause of nail spots

Mycosis refers to an infection caused by fungi—most often from the dermatophyte family. These colonize the skin or nails, on the hands or feet. Nail fungus is called onychomycosis.

First, a whitish or yellowish spot appears, which progresses over time. The nail becomes thicker, cracks, or crumbles. Mycosis never heals spontaneously and requires appropriate treatment. Various products such as nail polish, gel, or antifungal ointment are available for sale.

Leukonychia due to disease

Certain diseases or health problems affect the nails. They can cause a whitish color to all or part of the nail, or lead to the appearance of white spots or lines. These include:

• Cirrhosis. In this case, the white marks appear more like horizontal lines;
• Kidney failure. The lower part of the nails turns white, while the upper part becomes more pink or pigmented;
• Heart failure;
• Psoriasis or diabetes;
• Certain cancer treatments can also weaken the nail and change its appearance and structure.

Don’t panic, however, if you notice the appearance of a white spot on your fingernails or toenails. These spots are not the first manifestation of the aforementioned diseases. They are most often the result of a previously diagnosed condition for which treatment is underway. However, they can guide or confirm your doctor’s diagnosis if you experience other symptoms suggestive of these diseases.
