Role of Janus Kinase Inhibitors in the Treatment of Alopecia Areata

    Korn Triyangkulsri, Poonkiat Suchonwanit
    TLDR Janus kinase inhibitors show promise in treating alopecia areata but need better topical formulations.
    The document reviewed the role of Janus kinase (JAK) inhibitors in treating alopecia areata (AA), an autoimmune condition causing hair loss. It highlighted that JAK inhibitors like tofacitinib and ruxolitinib showed promise in promoting hair regrowth, with studies reporting significant improvements in many patients. For example, a study with 90 patients treated with tofacitinib showed 20% were complete responders and 38.4% were intermediate responders. However, hair loss often recurred after stopping treatment, and side effects included infections and liver enzyme elevations. The document emphasized the need for further research to confirm long-term efficacy and safety.

      Key treatments for hair preservation include minoxidil, finasteride/dutasteride, and microneedling, with additional options like specific shampoos, oils, biotin, zinc, tretinoin, clascoterone, and low-level laser therapy. Maintaining a healthy lifestyle, reducing stress, and addressing nutrient deficiencies can also support hair health.

      The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.
