title: Loose anagen hair syndrome: an unusual cause of alopecia of cosmetic importance only.
abstract: A 5-year-old girl was referred to our clinic because of a 5-month history of diffuse hair loss. Her hair was light brown and dull with evident patches of alopecia. There were no signs of scalp inflammation or scarring. A hair pull test revealed multiple hairs, easily and painlessly extracted. Light microscopic examination and trichogram were consistent with loose anagen hair syndrome. This is an unusual benign hair disorder of childhood that improves spontaneously with aging.
