Hi. It might be an allergic reaction to hair dye. There are a number of methods you can try to treat your symptoms at home. Try one of these options:
1. If you have an immediate, mild reaction to the dye, rinse it off immediately and thoroughly with warm water and mild soap or mild shampoo.
2. Apply a solution of potassium permanganate to the affected area. This can help fully oxidize PPD. PPD only causes allergic reactions when it’s in a partially oxidized state.
3. Treat contact dermatitis symptoms, such as skin rash or itching, with an over-the-counter, topical corticosteroid skin cream. These can be used on the face, neck, and other parts of the body, but should not be used near or in the eyes or mouth.
4. Use shampoos containing topical corticosteroids, such as Clobex, on your scalp.
5. Apply hydrogen peroxide. It’s a mild antiseptic and may help calm the skin and reduce irritation and blistering.
6. Take an oral antihistamine, such as Benadryl, to help reduce skin inflammation and itching.
If your symptoms don’t improve, or if they get worse or cause you distress that interferes with your ability to function, call your doctor immediately.
