OMIM®: 617252

Definition

Uncombable hair syndrome (UHS) is characterized by silvery, blond, or straw-colored scalp hair that is dry, frizzy, and wiry, has a characteristic sheen, stands away from the scalp in multiple directions, and is impossible to comb. This hair shaft disorder occurs in children and improves with age. The hair growth rate can range from slow to normal (summary by U. Basmanav et al., 2016). For a general phenotypic description and a discussion of genetic heterogeneity of UHS, see UHS1 (191480). [from OMIM]
