Introduction

Nail layering can be caused by factors such as nutritional deficiencies, lack of moisture, and fungal infections. It is recommended to promptly visit a hospital for a detailed examination and receive targeted treatment based on the specific condition. Specifically: in addition, prolonged exposure to chemicals—such as nail polish, laundry detergent, and cleaning agents—which are highly alkaline substances, may damage the nails and lead to nail layering.

Nail layering can be caused by factors such as nutritional deficiencies, lack of moisture, or fungal infections. It is recommended to seek timely medical evaluation at a hospital for a detailed examination and targeted treatment based on the specific cause. Specific analyses are as follows:

1.

Lack of Moisture

If a person habitually drinks little water, the body may fail to deliver sufficient moisture to the nails, potentially leading to nail layering. Drinking more water regularly and consuming fresh fruits and vegetables can benefit overall health.

2. Nutritional Deficiencies

Unbalanced diets may lead to insufficient intake of essential nutrients such as vitamins and trace elements, depriving the nail matrix cells of adequate nourishment. This can result in abnormal nail growth and layering. Under medical guidance, treatments may include oral medications such as calcium gluconate zinc oral solution, He Lu vitamin pills, or licorice zinc granules. Additionally, maintaining a varied diet rich in vitamins and trace elements is important.

3. Fungal Infection

If nails are infected by fungi, resulting in onychomycosis, symptoms such as nail thickening, layering, and cloudiness may occur. It is advisable to visit a hospital for fungal testing to confirm diagnosis. Under medical supervision, treatment may involve oral itraconazole capsules combined with topical antifungals such as ketoconazole cream or itraconazole cream.

Besides the above, prolonged exposure to chemicals such as nail polish, laundry detergents, and cleaning agents—strongly alkaline substances—can damage the nails and lead to nail layering.
