Both hypothyroidism and hyperthyroidism can cause dry, brittle, slow-growing nails. Reviews show higher rates of nail changes in thyroid patients.

Fast fix:
Ask your doctor for a simple blood test (TSH, T4, T3)
Proper thyroid treatment often restores nail health (timeline varies)
8. Psoriasis or Eczema
These skin conditions frequently affect nails, causing pitting, ridges, or separation.
Signs: Pitted nails, discoloration, or thickening.
Fast fix:
See a dermatologist for targeted treatment (topical or systemic)
Nail improvement often follows skin improvement (4–12 weeks+)
9. Fungal Infections
Onychomycosis can make nails thick, crumbly, yellow, or brittle.
Signs: Yellow/brown discoloration, thickening, debris under nail.
Fast fix:
Over-the-counter antifungal creams for mild cases
Prescription oral or topical meds for moderate–severe (dermatologist visit recommended)

Keep nails trimmed short
Moisturize cuticles twice daily with oil or thick cream
Avoid using nails to open cans/packages
