@drdavidmorris: Why does hair suddenly fall out in round patches? A smooth, circular bald spot may be a sign of alopecia areata, an autoimmune condition in which immune cells mistakenly attack hair follicles. But researchers are investigating another interesting connection: the relationship between the nervous system, stress-related signaling, and immune activity around growing hair follicles. A recent mouse study explored how sympathetic nerve activity may contribute to disrupting the protective environment around hair follicles. However, this proposed mechanism has not yet been confirmed in humans. Stress may be relevant, but it isn't the only possible factor behind alopecia areata. If you notice sudden patchy hair loss, consult a dermatologist to confirm the cause and discuss treatment options. 👉 If you noticed a sudden bald patch, would you first suspect stress, genetics, or an immune-related condition? #alopeciaareata #alopecia #hairloss #patchyhairloss #autoimmunehealth #immunehealth #hairfollicles #nervoussystem #stressandhealth #scalphealth #healthtok #murfreesboro #functionalmedicine #magnoliamedicalcenter #rootcause #fyp #viral
