Nail disorders range from cosmetic (brittle nails) to serious (suspicious pigmented streaks needing atypia assessment). Diagnosis matters — fungal nails need oral antifungals, psoriatic nails need different therapy, deficiency-driven brittleness needs supplementation.

Nail Disorders — FAQ
What conditions affect nails?
Fungal infection (onychomycosis), psoriasis, eczema, brittle nails (often nutritional/thyroid), pigmented streaks (need atypia assessment), ingrown nails (see ingrown toenail).
Treatment for fungal nails?
Oral antifungals (terbinafine 12 weeks for toenails, 6 weeks for fingernails). Topicals alone rarely work for nail fungus — they cannot penetrate the nail plate.
When is a dark streak under nail concerning?
Sudden new dark band, especially on a single nail, in adults — needs urgent dermoscopic evaluation. Could be benign melanonychia or rarely subungual melanoma.
Why are my nails brittle?
Iron deficiency, vitamin D/B12 deficiency, hypothyroidism, biotin deficiency, frequent water exposure, harsh nail products. We test and address underlying cause.
