What Are The Side Effects Of Using Hair Dye?

husband used Just for Men mustache and beard dye, now his face has blown up and it is oozing, he is not having trouble breathing, but is in pain. I given him 800 mg of Motrin, 50mg of Benadryl and he put sylvadane cream on to try to stop the burning feeling and pain....nothing is working..I suggested he go to 24hr center or hospital for steroid shot but he wont go...anything else we can try?
