Frontal fibrosing alopecia (FFA) is a primary cicatricial alopecia first described by Kossard in 1994. It is considered a clinical variant of lichen planopilaris (LPP). In the last two decades, there have been an explosion of cases worldwide. While predominately seen in Caucasian, post-menopausal women, it has been reported in various ethnicities including African-Americans, Hispanics, Asians, and Indians as well as in pre-menopausal women and men.1-5 Characterized by progressive, scarring frontotemporal hair loss with perifollicular erythema, follicular keratinization, and reduced follicular orifices, the most common finding is bandlike recession of the scalp hairline.1-5 Accompanying features include eyebrow thinning, eyelash loss, body hair loss, facial papules, lonely hairs, and occipital alopecia.1-5 While typically asymptomatic, pruritus and trichodynia can occur. Eyebrow thinning often presents prior to scalp hairline regression and has been seen with milder hairline regression compared to individuals who do not experience eyebrow thinning first.2-4 Other dermatoses seen in patients with FFA include lichen planus on regions other than the scalp and lichen planus pigmentosus in non-Cacuasians.
