Receding hairline

This patient had frontal fibrosing alopecia (FFA), a subtype of lichen planopilaris (LPP), or follicular lichen planus. LPP causes cicatricial (scarring) alopecia where the follicular epithelium is replaced with connective tissue and the hair follicle is permanently lost. LPP is caused by lymphocytic inflammation that initially presents as perifollicular erythema, with scale and keratotic plugs, and later progresses to scarring. If there is uncertainty in the diagnosis, biopsy can be helpful.

The LPP subtype, FFA, usually occurs in postmenopausal women. It follows a distinctive pattern, as in this patient, where the hair is progressively lost along the frontoparietal hair line (and sometimes the eyebrows). A careful physical examination reveals smooth skin where follicles are lost and there is erythema around the base of the hairs due to active inflammation and keratotic plugging. The specific mechanism of FFA is poorly understood, and hormones may play a role, in addition to the inflammatory response.

The goal of treatment is to arrest the progression of additional hair loss (which usually is permanent). Intralesional steroid injections, which also are used for alopecia areata, are the most common therapy. Triamcinolone 2.5 to 5 mg/mL is injected in the affected dermal layer of the scalp. Oral finasteride (a 5-alpha-reductase inhibitor to decrease androgens) 1 mg/d can be helpful, as can oral hydroxychloroquine 200 mg bid.

Once the inflammation has subsided, treatment can be discontinued. Hair transplantation has been used, but often fails due to the inflammatory scarring process. Our patient noted that her disease process had been stable and declined treatment.
