Brittle nails can be a frustrating and sometimes concerning condition that affects many people. These fragile nails tend to split, peel, or break easily, making everyday tasks challenging and impacting both function and appearance. Understanding the underlying causes and effective treatment options is crucial for maintaining healthy nail strength and appearance.
While occasional nail problems are common, persistent brittleness may signal various factors ranging from environmental conditions to underlying health issues. This comprehensive guide will help you understand what causes brittle nails, how to treat them effectively, and when to seek professional medical attention.

Frequently Asked Questions
What are the most common causes of brittle nails and how can I tell if mine are due to dryness or excess moisture? Dry brittle nails typically show vertical splitting and feel rough, while moisture-damaged nails tend to peel in horizontal layers. Common causes include frequent washing, chemical exposure, and environmental factors. Examine your daily activities and nail appearance to determine the likely cause.
How can I strengthen brittle nails with home care or supplements like biotin? Strengthen nails through regular moisturizing, protective measures, and proper nutrition. Biotin supplements may help, but consult your healthcare provider first. Use cuticle oil daily and protect hands from harsh chemicals.
Can brittle nails be a sign of an underlying health condition such as iron deficiency or thyroid problems? Yes, brittle nails can indicate underlying health issues including thyroid disorders, iron deficiency anemia, and other nutritional deficiencies. If nail problems persist despite proper care, consider medical evaluation to rule out these conditions.
What lifestyle changes help prevent or reduce nail brittleness from frequent handwashing or exposure to chemicals? Wear protective gloves during cleaning or dishwashing, use gentle soaps, apply hand cream after washing, and maintain proper nail length. Consider using a humidifier in dry environments and limit exposure to nail polish removers.
When should I see a doctor about brittle nails that do not improve with usual moisturizers and protective measures? Seek medical attention if brittleness persists for several months despite proper care, if you notice significant changes in nail appearance, experience pain, or suspect an underlying health condition. Also consult a doctor if nails separate from the nail bed or show signs of infection.
