February 2025 in “International Journal of Molecular Sciences” In this study using a mouse model, RIPK1 inhibitors were found to delay the onset of alopecia areata, reduce immune cell numbers in affected skin, and increase hair length, indicating a potential therapeutic role in preventing alopecia areata.
In this mouse model study, researchers observed that RIPK1 inhibitors delayed the onset of alopecia areata by modulating immune cells, specifically dendritic and CD8+ T cells, and increased hair length in organ culture mimicking the condition.

December 2018 in “Dermatology” This study found that oral JAK inhibitors, ruxolitinib and tofacitinib, are effective and well-tolerated for treating severe alopecia areata, with a similar degree of hair regrowth and relapse rates, but ruxolitinib induced faster initial hair regrowth.
