1. Genetics

Nail splitting, also known as onychoschisis, is a common condition that can affect people of all ages. It occurs when the nail becomes weak and brittle, causing it to split or peel into layers. There are many factors that can contribute to nail splitting, including genetics, nutritional deficiencies, and environmental factors.

Genetic predisposition: Some people are more likely to have nail splitting than others due to their genes. This is because genes play a role in determining the thickness and strength of the nails. People who have thin, weak nails are more likely to experience nail splitting.
Family history: If you have a family history of nail splitting, you are more likely to develop the condition yourself. This is because genes are passed down from parents to children.
Genetic disorders: Certain genetic disorders, such as ectodermal dysplasia and epidermolysis bullosa, can also cause nail splitting.

If you are concerned about nail splitting, it is important to see a doctor to rule out any underlying medical conditions. Treatment for nail splitting will depend on the cause of the condition.

2. Nutritional deficiencies

Nutritional deficiencies are a common cause of nail splitting. This is because vitamins and minerals are essential for the growth and health of nails. When the body does not have enough of these nutrients, the nails can become weak and brittle, making them more likely to split.

Biotin: Biotin is a B vitamin that is essential for the health of the hair, skin, and nails. A deficiency of biotin can lead to nail splitting, as well as other symptoms such as hair loss and skin rashes.
Iron: Iron is a mineral that is essential for the production of red blood cells. A deficiency of iron can lead to anemia, which can cause nail splitting, as well as other symptoms such as fatigue and shortness of breath.
Calcium: Calcium is a mineral that is essential for the strength of bones and teeth. A deficiency of calcium can lead to osteoporosis, which can also cause nail splitting, as well as other symptoms such as bone pain and fractures.

3. Environmental factors

Harsh chemicals can be found in a variety of everyday products, including nail polish removers, cleaning products, and detergents. These chemicals can damage the nails by stripping away their natural oils and weakening the keratin protein that makes up the nail. This can lead to nail splitting, as well as other problems such as nail discoloration and dryness.

Cleaning products: Many cleaning products contain harsh chemicals, such as bleach and ammonia. These chemicals can damage the nails by stripping away their natural oils and weakening the keratin protein that makes up the nail. This can lead to nail splitting, as well as other problems such as nail discoloration and dryness.
Detergents: Detergents are another common source of harsh chemicals that can damage the nails. Detergents can strip away the nails' natural oils, making them dry and brittle. This can lead to nail splitting, as well as other problems such as nail discoloration and peeling.

If you are concerned about the effects of harsh chemicals on your nails, there are a few things you can do to protect them. First, wear gloves when using harsh chemicals. Second, rinse your nails thoroughly with water after using harsh chemicals. Third, apply a moisturizer to your nails after using harsh chemicals.

4. Trauma

Trauma to the nails is a common cause of nail splitting. This can occur from a variety of sources, including biting or picking the nails, as well as from other injuries, such as stubbing the toe or getting a nail caught in a door. When the nail is injured, it can become weak and brittle, making it more likely to split.

Nail biting: Nail biting is a common nervous habit that can damage the nails. When you bite your nails, you are essentially tearing away at the layers of the nail, making it weaker and more likely to split.
Nail picking: Nail picking is another common habit that can damage the nails. When you pick at your nails, you are creating small tears in the nail, which can weaken the nail and make it more likely to split.
Other injuries: In addition to nail biting and picking, other injuries can also damage the nails and make them more likely to split. This can include injuries such as stubbing the toe, getting a nail caught in a door, or getting a nail cut too short.

If you are concerned about nail splitting, it is important to avoid injuring your nails. This means avoiding biting or picking your nails, as well as taking care to protect your nails from other injuries.

5. Medical conditions

Nail splitting, also known as onychoschisis, is a common condition that can affect people of all ages. It occurs when the nail becomes weak and brittle, causing it to split or peel into layers. While there are many factors that can contribute to nail splitting, including genetics, nutritional deficiencies, and environmental factors, certain medical conditions can also be a cause.

Thyroid disease: Thyroid disease is a condition that affects the thyroid gland, which is responsible for producing hormones that regulate metabolism. When the thyroid gland is underactive (hypothyroidism), it can lead to a number of symptoms, including nail splitting. This is because hypothyroidism can cause the nails to become dry and brittle, making them more likely to split.
Psoriasis: Psoriasis is a chronic autoimmune condition that causes the skin to become red, scaly, and itchy. Psoriasis can also affect the nails, causing them to become thick, discolored, and pitted. In some cases, psoriasis can also cause nail splitting.
Eczema: Eczema is a chronic skin condition that causes the skin to become dry, itchy, and inflamed. Eczema can also affect the nails, causing them to become weak and brittle, making them more likely to split.
Lichen planus: Lichen planus is a chronic inflammatory skin condition that can affect the skin, nails, and mucous membranes. Lichen planus can cause a variety of nail problems, including nail splitting, discoloration, and thinning.

If you are experiencing nail splitting, it is important to see a doctor to rule out any underlying medical conditions. Treatment for nail splitting will depend on the cause of the condition.

6. Medications

Chemotherapy drugs are a common cause of nail splitting. Chemotherapy drugs are used to treat cancer, and they work by killing cancer cells. Unfortunately, chemotherapy drugs can also damage healthy cells, including the cells in the nails. This damage can lead to nail splitting, as well as other nail problems, such as discoloration and thinning.

If you are experiencing nail splitting, it is important to see a doctor to rule out any underlying medical conditions. Treatment for nail splitting will depend on the cause of the condition. In the case of chemotherapy-induced nail splitting, treatment will focus on managing the side effects of chemotherapy and protecting the nails from further damage.

Here are some tips for protecting your nails from chemotherapy-induced damage:

Wear gloves when handling chemotherapy drugs.
Avoid using harsh chemicals on your nails.
Moisturize your nails regularly.
Keep your nails short and filed smooth.
