The role of platelet-rich plasma therapy in refractory folliculitis decalvans

This is the authors' abstract. We don't add key points for this paper.

Folliculitis decalvans (FD) is a rare, chronic primary scarring alopecia that classically presents with perifollicular pustules, scaling, crusting, and tufted hair in the affected areas of the scalp, accompanied by pruritus or pain.1 The cause of FD remains unclear; however, on histopathology, it presents as a predominantly neutrophilic inflammatory process targeting hair follicles, resulting in irreversible damage and permanent hair loss.1
