Frontal Fibrosing Alopecia

Frontal fibrosing alopecia (FFA) is a primary lymphocytic cicatricial alopecia with a distinctive clinical pattern of hair loss characterized by the progressive recession of the frontotemporal hairline. This particular form of alopecia currently is considered a variant of lichen planopilaris because it is often accompanied by the presence of cutaneous and/or mucous membrane lichen planus in patients.
