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.
