Studysummary This case report suggests that nonsynchronized segmented heterochromia in black scalp hair in a 14-year-old girl may represent premature greying unrelated to deficiencies in iron, copper, zinc, or protein. Our plain-language summary of this paper — not a Tressless recommendation.
A 14-year-old girl exhibited nonsynchronized segmented heterochromia in her black scalp hair over a 2-year period, without any associated iron deficiency anemia, vitiligo, or alopecia areata, and with normal serum iron, copper, zinc, and protein levels. This case was considered the first reported instance of this condition in black scalp hair, suggesting it as a presentation of premature greying.
