Loose anagen hair syndrome with diffuse woolly hair phenotype: A rare association

Abstract

Loose anagen hair syndrome (LAHS) is an underestimated cause of noncicatricial alopecia among children, manifesting as thin, sparse or fine hair. We report a case of LAHS clinically presenting as diffuse woolly hair, an association rarely described in the literature. In addition, we review the clinical as well as genetic link between these two enigmatic hair disorders and hypothesize that both may be associated in a yet unknown manner.
