How many times a day should I wash my hair?

A healthy scalp once a day

For dry scalp, once every 1-2 days

They say it is recommended to wash your hair twice a day if you have an oily scalp.

It is best to wash your hair at an appropriate frequency according to your scalp type. If you have no particular scalp issues, washing your hair every day is fine. However, if you have a dry scalp that stings or itches when you wash it, washing it once every 1 to 2 days is acceptable.

If you have an oily scalp that gets greasy by evening even after washing your hair in the morning, I recommend washing it twice a day. In particular, it is said that if you do not wash your oily scalp, pollutants such as dead skin cells and dust accumulate on the sebum, making it easier for bacteria to multiply. Since there is a high risk of scalp inflammation, please wash your hair at least once a day.
