What should I do if my ammonia-free hair dye is causing a severe allergic reaction with a week of scalp redness, itching, and new swelling on my forehead, even after taking allergy medicines like Cetricip or Allegra?
Since the redness, itching, and new swelling on your forehead have lasted a week and are not improving with cetirizine (Cetricip) or fexofenadine (Allegra), it is very important that you see a healthcare provider or dermatologist promptly. Even ammonia-free hair dyes can contain other sensitizing ingredients. The swelling suggests a stronger inflammatory response that typically requires a prescription treatment, like a topical or oral corticosteroid, which over-the-counter antihistamines cannot fully resolve. Please avoid scratching and do not apply any more hair products. A doctor can safely guide your recovery.
