What is (are) Uncombable hair syndrome ?
Uncombable hair syndrome (UHS) is a rare disorder of the hair shaft of the scalp. It usually is characterized by silvery-blond or straw-colored hair that is disorderly; stands out from the scalp; and cannot be combed flat. It may first become apparent from 3 months of age to 12 years of age. UHS is likely inherited in an autosomal dominant manner with reduced penetrance. A responsible gene has not yet been identified. The condition often spontaneously regresses in late childhood.
