Pityriasis amiantacea (also known as Tinea amiantacea) is an eczematous condition of the scalp resulting in hair loss in which thick tenaciously adherent scale infiltrates and surrounds the base of a group of scalp hairs.Pityriasis amiantacea was first described by Alibert in 1832. Pityriasis amiantacea affects the scalp as shiny asbestos-like (amiantaceus) thick scales attached in layers to the hair shaft. The scales surround and bind down tufts of hair.
