Onychorrhexis is a common nail condition which is a normal part of aging. It appears as longitudinal ridges with furrows on the nail plate, that on some occasions may lead to splitting at the free edge of the nail.
While it is common in older people, there are a number of conditions that can also cause it such as lichen planus, iron deficiency anemia, eating disorders, arthritis and psoriasis. An excessive use of nail polish remover can cause onychorrhexis.
There is no treatment for onychorrhexis except for any treatment directed at any underlying condition. This may lead to an improvement of the nail appearance.
It is important that the nail is cut regularly as it is much more prone to splitting or chipping that may become painful. If the nail is kept short, this is less likely.
