Hair coloring may lead to contact dermatitis, hair damage and other hazards.
1. Contact dermatitis: In the process of hair coloring, the chemical ingredients contained in the hair dye will come into direct contact with the surface of the scalp, causing damage to the scalp, thus causing contact dermatitis, redness and swelling of the scalp, itching, burning pain, if the symptoms are more serious, there may also be erythematous swelling of the scalp and face, and pus infection may also occur.
2. Hair damage: Hair coloring may lead to dry and frizzy hair, soft and easy to break, and finally lead to hair loss.
Hair dye may also have other harmful effects on the human body, so it is recommended to minimize hair dyeing and control it to once or twice a year. If you are not comfortable with hair coloring, go to the hospital for treatment.
