Introduction
Nail splitting may be caused by frequent exposure to chemicals, nutritional deficiencies, fungal infections, or other factors. Autoimmune diseases can also lead to this condition. If a patient consistently experiences nail splitting, the underlying cause should be identified and treated accordingly. In daily life, keeping nails dry and avoiding contact with chemical substances can help prevent nail splitting.
Nail splitting may be caused by frequent exposure to chemicals, nutritional deficiencies, fungal infections, and other factors. Specific causes are as follows:
1. Frequent exposure to chemicals
Long-term contact with chemical products such as detergents, cleaners, and paints can damage the nails and lead to splitting. It is important to reduce exposure to these substances and use protective measures like gloves to safeguard the nails.
2. Nutritional deficiencies
Nails tend to split when lacking essential nutrients such as calcium, iron, zinc, and sulfur. This condition can be prevented and treated by improving diet and consuming more foods rich in these nutrients. Additionally, taking oral multivitamin and mineral supplements—such as vitamin E, calcium, magnesium, and zinc—can also be beneficial.
3. Fungal infection
Nail fungal infections can cause symptoms including thinning, deformation, and splitting of the nails. Treatment typically involves antifungal medications, either topical or oral. Commonly used medications include topical agents like miconazole and terbinafine, and oral drugs such as itraconazole.
In addition, autoimmune diseases may also cause the above-mentioned symptoms. If a person consistently experiences nail splitting, it's important to identify the underlying cause and receive appropriate treatment. In daily life, keeping nails dry, avoiding excessive trimming, and minimizing contact with chemical products can help prevent nail splitting.
