Black line on the nail is a common problem. It may appear suddenly or it may develop over time. Some people do not notice any change in their nails until they are older, while others have them completely white when they were young. Whatever the case, the black line on your nails can make you feel sad and even embarrassed. There are many reasons why you might experience black line on your nails. They include:
1) Your nails are too thick.
If your nails are thicker than 1mm (0.04 inches), then there is a good chance that you will experience black line on your nails.
This could be due to genetics, stress, poor hygiene or other factors that cause excessive growth of hair follicles in the nail beds and cause them to grow outwards instead of inward like they should.
2) You have a genetic condition called alopecia areata.
Alopecia areata is caused by a lack of sunlight exposure during childhood. This means that if you live in a place where the sun does not shine regularly, then your nails will likely turn black because the pigment cells in your skin cannot produce enough melanin to protect against UV rays.
This condition affects both men and women equally, but it is more common among girls than boys. The black color of the nails will spread from one finger to another and then to the hands and feet if left untreated. If this happens, there is a possibility that the pigment cells in the skin may start to grow outwards instead of inwards like they should. The result is usually ugly and unattractive.
3) You have a fungal infection of the nails (Onychomycosis).
This condition involves presence of fungus under or around the nails. It causes a discoloration of the nails and makes them very brittle.
The black line on your nails is probably due to this condition, which can be treated with anti-fungal pills or creams available over the counter at any drug store.
If you think that the black line on your nails is due to any of the three conditions mentioned above, then you should seek medical attention immediately. Ignoring these conditions could lead to more serious health problems in the future.
