A girl with loose anagen hair syndrome and concurrent uncombable hair syndrome

Loose anagen hair syndrome (LAHS) is characterized by easily extractable anagen hairs that lose the inner and outer root sheath during removal. Patients with uncombable hair syndrome (UHS) have unruly, “spun-glass” hair that cannot be combed flat. In 1996, Boyer et al reported an instance of LAHS mimicking uncombable hair. In 2005, Lee et al reported another instance of LAHS with concurrent features of uncombable hair syndrome. We report another patient with findings suggestive of both syndromes.
