What Are the Types and Causes of Fingernail Ridges?
Various studies show that vertical ridges are commonly caused by aging. Like the skin, the fingernails and nail beds also start to change with age.
Just as the skin may show signs of aging, the fingernails and nail beds may also start to change with age. In some cases, the nails may become:
- Break easily
- Become thicker or thinner
- Begin to split
- Lose their smooth shape
- Fissure
The nails may also begin to form any number of vertical ridges as they grow. The ridges run from the rip of the finger down to the bottom of the nail. They are usually harmless and not a cause for health concerns. It would help to contact a dermatologist to help in cases where symptoms may lead to pain or a structure that you are not comfortable with.
