Hair Regrowth in a Child with Seasonal Alopecia Areata While Receiving Subcutaneous Aeroallergen Immunotherapy: A Case Report
TLDR Immunotherapy helped a 5-year-old boy regrow hair and prevent seasonal alopecia areata.
A 5-year-old male with seasonal alopecia areata, linked to rhinitic allergy flares, experienced significant hair regrowth while undergoing subcutaneous aeroallergen immunotherapy. Initially presenting with near-complete hair loss during spring and fall, the child showed sensitivity to various allergens. After starting immunotherapy, hair growth began on his arms and legs within 3 months, leading to complete resolution of scalp alopecia. Over four years of treatment, seasonal alopecia did not return, although minor occipital hair shedding occurred during rhinitic flares. This case suggested that seasonal allergens might trigger alopecia areata, and immunotherapy could be an effective treatment.
