What are T-cells?
T-cells are a type of white blood cell that plays a central role in immune response, including recognizing and attacking infected or abnormal cells.
In autoimmune hair loss conditions like alopecia areata, T-cells mistakenly target healthy hair follicles.
Red light therapy has demonstrated immune-modulating properties that may reduce T-cell-driven inflammation and support follicular recovery in certain autoimmune cases.
