Why does it look like there are cracks on my fingernails?
user
There could be several reasons why your fingernail have some cracks, such as dryness or brittleness of the nail plate due to a deficiency in vitamin D. It's also possible you have been exposed to something harmful, such as harsh chemicals or detergents while cleaning your hands. It is important that you wash them thoroughly with soap and water after exposure to any potentially hazardous substances in order to prevent further damage to the nail bed.

It is important that you see a dermatologist or doctor to determine the cause of these cracks and receive proper treatment if necessary.
