Lichen planopilaris epidemiology: a retrospective study of 80 cases

Lichen planopilaris is a rare inflammatory condition that results in patchy progressive permanent hair loss mainly on the scalp. Three forms are recognised:. Lichen planopilaris usually affects young adult women, although the age range is wide and it also affects men.

Lichen planopilaris is suspected on the clinical presentation and careful examination of the mouth, nails and skin for evidence of lichen planus elsewhere.

Treatment should be sought and provided early as no treatment recovers hairs that have been lost and replaced by scarring. The aim of treatment is to slow progression of the disease and relieve symptoms. Hair loss may continue, although at kiquen slower rate.

Response to treatment is variable and some published studies contradict others as to the efficacy. The best patients can expect is to stop progression of hair loss and to minimise scalp discomfort.
