Dark, Brittle Nails? Uncover Hidden Health Issues & Prevention Tips!

• Dark and brittle nails can indicate underlying health problems, not just cosmetic concerns.
• Deficiencies in iron, biotin, vitamin B12, and vitamin D are common culprits, alongside frequent water exposure.
• Fungal infections like Onychomycosis cause black, brittle nails; a KOH Mount test confirms diagnosis.
• Prevention includes a diet rich in essential nutrients (eggs, fish, spinach, millets) and 30 minutes of daily sun exposure.
• Consult a doctor for diagnosis and treatment, which may involve anti-fungal tablets/creams for infections.

Why It Matters: Dark, brittle nails signal potential nutrient deficiencies or fungal infections; seek medical advice for diagnosis and treatment.
