September 2023 in “Clinical, cosmetic and investigational dermatology” This genome-wide association study identified several genetic markers, including specific SNPs and HLA genotypes, associated with alopecia areata susceptibility in the Taiwanese population, highlighting key pathways involved in immune response and offering insights into the genetic origins of this autoimmune condition.
March 2024 in “International Journal of Cosmetic Science” This study observed that dandruff-affected scalp skin has increased T-cell infiltration in the epidermis and a reduction in the hair follicle's physiological immune privilege, particularly in the suprabulbar outer root sheath area, indicating a distinct immune microenvironment compared to healthy scalp.
