Lichen planopilaris is a type of scarring (cicatricial) alopecia that causes hair loss and inflammation. It is a follicular form of lichen planus, a common yet chronic mucocutaneous disease which affects hairier areas of the body.
Cause
The cause of the condition is believed to be auto-immune like alopecia areata, although there is also a link between lichen planopilaris and certain drugs. Exposure or allergic reaction to certain types of chemical or drug can cause what is known as “lichenoid” reactions weeks or even years after contact, although the cause of these reactions is not yet known.
The condition is known to affect middle-aged adults, appearing as distinct patches of hair loss, scarring and inflammation surrounding hair follicles. In some cases, hair loss can be permanent.
Other symptoms include reddish purple – or occasionally, white and shiny – papules (small, elevated areas) on the skin. These papules are generally uneven in shape and can often be very itchy for the sufferer.
Treatment
Known treatments for cases of lichen planopilaris include oral steroids, Plaquenil, Accutane and topical steroid liquids.
If you suspect you, or a family member, has the condition, you should see your doctor immediately for a formal diagnosis.
