Summary: | Immunotherapy for skin conditions has a long and successful history. While the main
strategy for treating inflammatory conditions is local or systemic immunosuppression,
immunotherapy aims to stimulate parts or all of the immune system to bring about a
therapeutic response. The immune system contains multiple, redundant avenues of checks
and balances, and some immune cells have immunomodulatory or regulatory roles. These
cells are targeted by immunotherapy in inflammatory skin conditions. Immunotherapy is
effective in treating some hair loss disorders, supporting recent findings that the hair cycle is
influenced by immune cells.
