What symptom is allergic to the smell of hair dye?
Hair dye allergy is usually the symptoms of skin redness, swelling, itching and rash in the head and limbs after hair dyeing. In severe cases, anaphylactic shock may occur, which is life-threatening. Hair dye allergy is protracted and difficult to treat, and will suffer from hair dye dermatitis (a kind of contact dermatitis).
According to the skin allergy symptoms caused by hair dyeing allergy, experts suggest that before hair dyeing, consumers should do an allergy test before hair dyeing. Before each hair dyeing, consumers should first choose a handful of hair behind the ear root for allergy test. If there is any abnormality, they can choose other brands to re test. If there is still allergy, they should give up hair dyeing.
Scalp itching can be relieved by chlorpheniramine. Of course, it needs to be treated slowly. Allergy needs time to be treated and recovered slowly. There is no need to worry about the intermediate process, because the hair dye is a chemical. It is suggested that patients should not dye their hair more than twice a year.
