How much does it cost to iron bangs?

How much it costs depends on what potion you use. The potion you use is better, less harmful to your hair, and slightly more expensive. If the medicine you use is ordinary and cheaper, it may cause more damage to your hair. 20 yuan is ok, but it is not recommended that lz only burn bangs, because bangs are easy to grow, so they usually don't last long. It's better to consider doing full hair, and the effect may be better ~
