Biologic treatments and hair loss: adverse effect, paradoxical immune reaction or consequence of the disease?

Hair loss under biologic treatment is real but rare and heterogeneous: telogen effluvium, paradoxical alopecia areata, inflammatory scalp psoriasis, infection or (rarely) scarring alopecia. The best-established signal concerns anti-TNF drugs (French pharmacovigilance: 52 cases, reporting odds ratio 3.0), rather a class effect. Dupilumab, on the contrary, can promote regrowth in some atopic patients. The right question is not 'should the biologic be stopped?' but 'which alopecia is it, is there another cause, and is the follicle threatened?'.
