Eight-character air bangs should be washed and blown frequently, and it is necessary to wash them once a day (people with long hair can choose to wash only bangs), but some people may not be able to carry them all day, but people who are lazy can spray dry the fog when they want to go out. Dry hair spray can keep your hair dry, or loose powder, and can also save bangs. A small amount can be applied to bangs and then blown with a hair dryer, which can basically cope with going out.
