A Case of Woolly Hair

Woolly hair is normal for most black people, but it is usually abnormal for persons of a non-African or non-Negroid background. A 5-year-old girl visited our clinic complaining of a hair abnormality. Her hair had been tightly curled, fine, and hypopigmented on the entire scalp since birth. Her uncle’s son had similar abnormalities of his scalp hairs. On the scanning electron microscopy, the patient’s hair revealed cuticular damage with splintering. To the best of our knowledge, this is the first description of a patient with woolly hair who has familial history in Korea.
