Key Takeaways

Alopecia areata is a chronic autoimmune disorder causing non-scarring hair loss due to immune system attacks on hair follicles.
Breakdown of immune privilege in hair follicles leads to infiltration by cytotoxic T cells, particularly CD8+ T cells.
Inflammatory cytokines like IFN-γ and TNF-α are key contributors to immune-mediated hair follicle destruction.
The chronicity of alopecia areata is linked to persistent immune dysregulation and genetic predisposition.

Panelists discuss how the epidemiology of alopecia areata (AA) varies across different patient populations, with certain forms of the disease being more prevalent in specific groups.
