Reviewed on 4/28/2022

Lichen planopilaris is a disease of the scalp caused by inflammation around the roots of the hairs. The inflammation is followed by scarring (fibrosis) and loss of the hair, leading to baldness of the affected area. The inflammatory process also may involve skin other than the scalp and the fingernails. It is thought to be autoimmune in nature.
