What symptom does dye hair allergy have a headache?

Hair dye allergy is allergic contact dermatitis caused by hair dye. Mild cases are characterized by swelling, itching and burning of the scalp. Severe cases are characterized by swelling of the scalp, neck and face, blistering, yellowing and even purulent infection. There is a chemical called "p-phenylenediamine" in hair dyes, which is easy to cause damage to human skin.

There is another possibility of headache after dyeing. The scalp is allergic to a certain drug of hair dye, and the scalp can't absorb it at all. The drug will act on the scalp, making the scalp feel numb and pungent, making the scalp uncomfortable.

Hair dye may also lead to leukemia and cancer and other major diseases. Hair dye will enter the blood vessels of the brain from the scalp. Once it enters the blood vessels of the brain, it will continue to circulate in the body. If it cannot be discharged, it will damage the hematopoietic stem cell lesions and cause diseases.
