March 2013 in “Gene” This study reported that the IL1A 4-bp indel polymorphism is associated with a reduced risk of alopecia areata in Chinese populations, possibly through miR-122 mediated regulation of IL-1α expression.
In this animal study, treatment with Trachyspermum copticum seed extract significantly altered IL-1 and KGF/FGF-7 gene expression, improving dermatitis and hair growth in mice compared to controls and corticosteroids.

January 2016 in “Journal of Investigative Dermatology” This study found that IL-6 knockout mice exhibited increased wound-induced hair neogenesis compared to wild-type mice, likely due to enhanced STAT3 activation facilitated by compensatory cytokine activity.
April 2026 in “Dove Medical Press (Taylor and Francis Group)” This study found that Myrtus communis leaf extract significantly decreased IL-1α and increased VEGF gene expressions in human keratinocytes, which may relate to the plant's traditional uses for hair loss and wound healing, though further research is needed to explore these effects.
