What Causes Peeling of a Child’s Fingernails?
Peeling of a child’s fingernails may result from vitamin deficiency, iron-deficiency anemia, or onychomycosis (fungal nail infection).

What Causes Peeling of a Child’s Fingernails?
Vitamin Deficiency: Excessive picky eating or selective eating habits in children may lead to inadequate intake of essential vitamins, resulting in vitamin deficiency. This can manifest as nail peeling and dry skin. Increasing consumption of vitamin-rich foods—such as oranges and grapefruits—may help. In more severe cases, supplementation with vitamin B1 tablets or vitamin C tablets may be recommended.
Iron-Deficiency Anemia: A common form of anemia, iron-deficiency anemia typically arises from insufficient dietary iron intake or excessive iron loss. Affected children may present with pallor, fatigue, and other systemic symptoms; nail abnormalities—including peeling—may also occur. Treatment should be guided by a physician and may include iron supplements such as ferrous gluconate oral solution or ferrous lactate syrup.
Onychomycosis: This is a fungal infection of the nail that can cause peeling. In advanced cases, nails may become cloudy or separate from the nail bed. Topical antifungal therapy—such as miconazole nitrate cream—may be prescribed under medical supervision; for severe infections, oral antifungals like itraconazole capsules may be added.
Maintain cleanliness and dryness of the nail area in daily care.
In fact, peeling at the edges of a child’s fingernails is not a normal occurrence. Therefore, parents should never overlook this symptom when observed in their child. Prompt identification of the underlying cause—and subsequent targeted intervention—is essential to ensure the child receives adequate nutrition and timely treatment.
