The term “woolly hair” refers to an abnormal variant of fine, tightly-curled hair that often exhibits decreased pigmentation. After the initial report of woolly hair by Gossage in 1907, Hutchinson et al. in 1974 further classified woolly hair into three variants: autosomal dominant hereditary woolly hair, autosomal recessive familial woolly hair and woolly hair nevus. Since then woolly hair has also been observed in association with several genetic conditions, most notably Noonan syndrome and cardio- faciocutaneous syndrome.
To our knowledge, there have only been two cases of woolly hair in the Korean dermatologic literature. We herein report a case of woolly hair in a 14-year-old Korean girl. suhagra 100
