3. Nutritional deficiencies
Although not the most common cause, certain nutrient deficiencies can affect nail health. A lack of zinc, iron, or certain vitamins can make nails more brittle and promote the appearance of spots.
A balanced diet generally helps to prevent this problem.
4. Infections or diseases
In rare cases, white spots can be linked to a fungal infection , skin problems, or certain internal diseases. However, these cases are much less frequent and are usually accompanied by other visible symptoms.
