Swollen eyes after hair dyeing are commonly caused by local inflammation and allergy in the eyes.
1. When dyeing hair, the hair dye may enter the eye and stimulate the conjunctiva and cornea of the eye to become inflamed, or when dyeing hair, you may use your hands to directly contact your eyes, which may lead to local bacterial infection and other pathogenic bacteria in the eyes, causing inflammation of the cornea and conjunctiva, which often manifests itself as redness and swelling of the eyes, increase in secretion, tearing and other discomforts.
2. When dyeing hair, because the skin of the eyelid is allergic to some chemical components in the hair dye, there is a perverse reaction, which can be manifested as redness and swelling of the eyelids, accompanied by itching and other discomforts.
It is recommended that the patient consult a doctor in time to clarify the cause of the disease and target treatment.
