Alopecia areata is an autoimmune disease of uncertain aetiology. However, it is known that genetic predisposition and environmental factors contribute to the onset of hair loss. Hair follicles are immune-privileged sites – able to tolerate the introduction of antigens without an inflammatory response.
No one (at least as far as we know) like’s the thought of losing their hair. It doesn’t matter if you are in your 20’s in the prime of your life or about to retire at the ripe old age of 65, a man or a woman, or even your sexual orientation. Hair loss is real and it doesn’t discriminate.
