New to Alopecia Areata? There is a guide in the encyclopedia. Read the guide → Studysummary In a case report, complete hair regrowth was observed in a patient with severe alopecia areata after treatment with deucravacitinib, a TYK2 inhibitor, suggesting new therapeutic avenues for alopecia areata despite TYK2 not being traditionally linked to this condition. Our plain-language summary of this paper — not a Tressless recommendation.
A patient with severe alopecia areata experienced complete hair regrowth after being treated with deucravacitinib, a selective TYK2 inhibitor. This result is notable because TYK2 is not typically associated with the pathogenesis of alopecia areata, indicating that TYK2 inhibition may have immunomodulatory effects. The case highlights the importance of investigating new pathways and off-target mechanisms for treating alopecia areata.
