June 2024 in “British Journal of Dermatology” This study observed that some patients experienced alopecia areata during dupilumab treatment for atopic dermatitis, but many regrew hair while continuing therapy.
July 2022 in “British Journal of Dermatology” This study found that epidermal growth factor receptor inhibitors used in cancer treatment induce a distinct inflammatory response in hair follicles, marked by immune privilege collapse and upregulation of inflammatory pathways.
March 2021 in “International Journal of Clinical Dermatology & Research” Dupilumab can help regrow hair in alopecia areata but stopping it may cause hair loss again.

December 2017 in “The journal of investigative dermatology. Symposium proceedings/The Journal of investigative dermatology symposium proceedings” This study suggests that targeting specific immune pathways, such as IL-12/23 and Th2 cytokines, may offer new treatment options for alopecia areata, a T-cell-mediated disease without current mechanism-specific therapies.
1 citations
,
January 2025 in “International Journal of Dermatology” This study found that in patients with alopecia areata and atopic dermatitis, 61.5% showed improvement with dupilumab treatment, but 38.5% experienced worsened or new-onset alopecia areata, with higher baseline IgE levels linked to better responses.
January 2024 in “bioRxiv (Cold Spring Harbor Laboratory)” In this study, the researchers found that deleting ceramide synthase 4 in the skin's epidermis alters stem cell differentiation, disrupting hair follicle structure and barrier function, potentially leading to immune responses similar to atopic dermatitis.
September 2025 in “Figshare” This study conducted a scoping review and meta-analysis revealing a complex chemokine profile in alopecia areata patients, with elevated Th1, Th2, and other immune pathway chemokines, suggesting broader immunomodulatory strategies may help address the disease's multifaceted immune dysregulation.
September 2025 in “Figshare” In this scoping review and meta-analysis, researchers found that patients with alopecia areata exhibit complex chemokine profiles, with elevated levels of Th1, Th2, and other immune pathway-associated chemokines, suggesting the potential for broad immunomodulatory strategies to address the disease's immune dysregulation.
September 2025 in “Figshare” In this scoping review and meta-analysis, researchers found that patients with alopecia areata show a complex serum chemokine profile, predominantly involving Th1- and Th2-associated chemokines, suggesting that broader immunomodulatory strategies might address the diverse immune dysregulation observed in the disease.
