Vertical nail splitting, also known as onychorrhexis, can be a sign of damage to the nail matrix, or the part of the finger that creates the nail. It can also be caused by nail fungus, psoriasis, or vitamin deficiency. Nails can also become weak and brittle due to overexposure to moisture, which can occur when doing dishes, washing hands, or from repeated nail polish use.

What You'll Learn

Vertical nail splits can be a sign of damage to the nail matrix
Vertical nail splits, also known as onychorrhexis, often occur with ageing. As you get older, your nails can become ridged, dry, brittle or thick, making them more prone to splitting. This is a normal part of the ageing process and is one of the most common causes of vertical nail splits.
However, vertical nail splits can also be a sign of an underlying health condition. For example, they have been linked to heart and circulatory diseases. This is because your blood delivers nutrients and oxygen to your tissues and cells, so problems with circulation can affect nail health.
Vertical nail splits can also be caused by injuries, skin conditions, vitamin deficiencies, nail infections and, less commonly, psoriasis.

Nails can become weak and brittle due to overexposure to moisture
Onychorrhexis is typically a cosmetic issue, but it can sometimes indicate an underlying health problem. For example, vertical nail splitting can be a sign of damage to the nail matrix, the part of the finger that creates the nail. Additionally, nail splitting can be a random occurrence or the result of a recent injury.
There are several factors that can contribute to nail splitting, including ageing, pregnancy, nail polish, injuries, and skin conditions. Nails can also split due to a nail infection, an underlying medical condition, or a vitamin deficiency. While clear nail polish or nail glue can temporarily fix a split nail, it is important to address the underlying cause to promote healthy nail growth.
To maintain strong and healthy nails, it is crucial to protect them from overexposure to moisture, which can lead to brittleness and splitting. Additionally, ensuring proper nutrition and addressing any underlying health conditions can help prevent nail splitting and promote overall nail health.

Ageing nails may also show other signs of deterioration, such as peeling, ridges, dryness and thickness. These symptoms are usually cosmetic annoyances and are not a cause for concern. However, vertical nail splits can sometimes indicate an underlying health problem, such as heart and circulatory diseases.
Nails can also split vertically due to temporary factors such as nail polish, injuries, skin conditions, nail infections and vitamin deficiencies. If you are concerned about the condition of your nails, it is best to consult a doctor or dermatologist. They will be able to advise on the best course of action to improve nail health and determine if any further steps are necessary.
