Because the university is very open, the teacher won't care whether you dye or not, but from a health point of view, you can dye, but try to dye as little as possible. From the student's point of view, it's up to you to decide whether to dye or not, because there is no rule in the university that you can't dye. In fact, on the university campus, management is not as strict as that of middle school, as long as it is not gaudy clothes, some colors are too bright or green and yellow, but the school allows some simple colors.

Matters needing attention in dyeing hair

1, don't dye your hair repeatedly for three months.

People who have dyed their hair within three months had better not dye it again. Because the hair dye contains a decoloring agent, this ingredient is harmful to the hair scales, and the damaged hair scales will become fragile and easily broken. If you dye your hair repeatedly within three months, the damaged hair scales will be damaged again and cannot be recovered.

Don't dye your hair if there are scratches on your scalp.

Remember not to wash your hair before dyeing it. First, the oil secreted by the scalp has a protective effect on the scalp. Second, you can avoid accidental scratches when washing your hair. If there is a wound on the scalp and then comes into contact with hair dye, it is easy to cause inflammation.
