Lichen planopilaris (also known as "Acuminatus," "Follicular lichen planus," "Lichen planus follicularis," and "Peripilaris") is a form of hair loss which involves scarring, a follicular form of lichen planus, and is considered to have an autoimmune cause. Lichen planopilaris is a distinct variant of cicatricial alopecia, a group of rare disorders which destroy the hair follicle, replace it with scar tissue, and cause permanent hair loss.

“The lichen on the rocks is a rude and simple shield which beginning and imperfect Nature suspended there. Still hangs her wrinkled trophy.”
—Henry David Thoreau (1817–1862)
