White hair rarely goes back. So when a 72-year-old woman's long-standing white hair began regaining pigment, it looked like the kind of aging surprise most people would welcome.
Her dermatologist saw something else. She also had frontal fibrosing alopecia (FFA), a form of scarring hair loss that typically pushes the hairline back and thins the eyebrows. The case, reported by Nicolò Rivetti of Istituto Clinico Beato Matteo in Vigevano, Italy, in JEADV Clinical Practice, argues that the unexpected return of color "may serve as a diagnostic clue."
