4. Health Conditions
Thyroid Diseases
Both hyperthyroidism and hypothyroidism can cause brittle nails. If you suspect your thyroid might be the issue, a simple blood test can help diagnose these conditions, and appropriate treatment can be administered.
Psoriasis
This skin condition can extend to the nails, causing pitting, abnormal nail growth, and splitting. Treating the underlying psoriasis can often improve nail health.
Fungal Infections
Fungal infections can damage the nail bed and cause nails to become brittle and split. Antifungal treatments are effective in resolving these infections.
