Highlighting the Link Between Lichen Planus Pigmentosus and Frontal Fibrosing Alopecia

FFA and LPPigm are difficult to treat and can be distressing for patients, especially when coexisting. The loss of follicular ostia in FFA is irreversible, and thus dermatologists need to diagnose and treat it early. Clinicians should be aware of the overlap between FFA and LPPigm and examine patients with LPPigm for FFA and vice versa, especially in patients with darker skin tones.¹⁰ As LPPigm frequently precedes FFA, its presence may serve as an early indicator of FFA onset and should prompt further evaluation. When coupled with other severity indicators of FFA, such as facial papules and the loss of eyebrows and eyelashes, concurrent LPPigm can be regarded as an adverse prognostic factor.⁵
