TLDR Minoxidil can cause allergic skin reactions, especially in those with underlying health issues.
This case report describes a 28-year-old woman with subclinical hypothyroidism and micronutrient deficiencies who developed allergic contact dermatitis (ACD) after using 5% topical minoxidil for approximately 50 days. Symptoms included pruritus of the ears and an erythematous, pruritic rash on the face, neck, and back. The condition resolved completely within one week after discontinuing minoxidil and using antihistamines and topical calamine, without the need for corticosteroids. The report emphasizes the importance of recognizing minoxidil-induced ACD, particularly when symptoms extend beyond the scalp, to prevent progression and ensure adherence to hair loss treatments.
