Fingernails (weak or brittle)
Synopsis
Weak or brittle fingernails are nails that crack, peel, split, or break easily, often due to nutritional deficiencies, frequent water or chemical exposure, aging, or underlying health conditions. While occasional nail fragility is common, persistent weakness may indicate deeper issues with keratin formation, hydration, or mineral balance.
Common causes include:
-
Frequent wet-dry cycles (handwashing, dishwashing, swimming)
-
Overuse of nail polish remover, acrylics, or harsh detergents
-
Nutritional deficiencies (especially biotin, iron, zinc, protein)
-
Thyroid imbalances (hypothyroidism is a major contributor)
-
Poor circulation or low oxygenation (e.g., anemia)
-
Aging, which slows down keratin turnover and moisture retention
-
Chronic dehydration or malabsorption conditions
The nail matrix, which generates new nail cells, is sensitive to nutritional status and overall health. Without proper support, nails become dry, thin, and prone to damage.
When to see a doctor:
If brittle nails are accompanied by hair thinning, fatigue, ridges, changes in nail color, or other systemic symptoms, it’s important to assess for thyroid disease, anemia, or nutrient malabsorption.
Natural Remedies
Moisturize Nails and Cuticles: Use oils like almond or jojoba to seal hydration and prevent splitting.
Wear Gloves for Wet Work: Protects nails from water and chemical exposure.
Limit Nail Polish Removers: Use acetone-free formulas and give nails time to recover.
Trim and File Regularly: Keeps nails strong and prevents splitting or peeling from catching.
Stay Hydrated: Proper hydration supports keratin strength and elasticity.
