White spots on finger nails are a common cosmetic issue, but there are several potential causes for their appearance.
Here are some of the most common:
1. Zinc Deficiency: Lack of zinc in the body can lead to white spots on nails as the mineral is crucial for healthy nail growth.
2. Fungal Infection: White spots on nails can be a sign of a fungal infection, which can also lead to thickening, discoloration and separation of the nail from the nail bed.
3. Injury: White spots on nails may be caused by a physical injury, such as banging your finger or dropping something heavy on it, which can cause blood to accumulate under the nail and cause a white spot.
4. Nail Polish: Using nail polish or remover can lead to white spots on nails if the chemicals in the product penetrate the nail.
5. Allergic Reaction: If you have an allergic reaction to a product, such as a hair dye or lotion, it can cause white spots to appear on your nails.
In most cases, white spots on nails are harmless and will grow out with the nail. However, if you have persistent or worsening symptoms, it is best to consult a doctor or dermatologist to determine the underlying cause and get appropriate treatment.
