Could recurrent, localized hair loss resulting in completely smooth patches of scalp skin indicate alopecia areata, and how does a prior positive response to topical corticosteroid, antifungal, and nutritional therapies affect this diagnosis?
Yes, recurrent, smooth patches of hair loss are very characteristic of alopecia areata, a common and highly manageable condition where the immune system temporarily pauses hair growth. Your previous positive response to a topical corticosteroid strongly supports this diagnosis, as these treatments help calm local inflammation so your hair can regrow. While nutritional support aids overall hair health, the corticosteroid response is the key clue here. I highly recommend consulting a dermatologist to confirm this and tailor a safe, effective plan for you.
