Inflammatory alopecia in patients on dupilumab: a retrospective cohort study at an academic institution

: Dupilumab targets IL-4Rα and is used for moderate-to-severe atopic dermatitis (AD). Prior reports have described new alopecia areata (AA),1 flaring of prior AA,2 as well as improvement or resolution of AA3 in patients treated with dupilumab. We conducted a retrospective cohort study to describe the natural history of prior or new inflammatory alopecia in patients on dupilumab.
