People who dye their hair are afraid of long black hair, which affects the aesthetic feeling of the overall shape. So in reality many people dye their hair once a month. This frequency is not recommended. High-frequency dyeing and perming is not only easy to cause damage to scalp and hair quality, but also easy to cause problems in other organs of the body, such as urinary system diseases, which increases the risk of cancer. Therefore, it is necessary to control the number of times of dyeing hair.
The upper limit of dyeing hair is 4 times a year, and it is usually recommended to dye hair 1-2 times a year. Don't dye your hair too much, so as not to pose a threat to your health.

At the same time, it is also necessary to avoid the hairdresser directly getting the hair dye on the scalp.
