Patches of scalp hair that turned white almost overnight
A 55-year-old woman presented with patches of scalp hair that had suddenly turned white. The patient characterized the change as happening “almost overnight.” Her scalp was completely asymptomatic. The woman, who was in good health, had been under stress but hadn’t received any recent shocks. She had no other signs or symptoms but expressed concern about the sudden whitening of her hair and what it might mean.
