If you want to straighten your bangs, you can buy your own potion. In fact, the hairdressing shop earns money from potions. Straightened parts are divided into 1 and No.2, 1 softens and No.2 sets. In addition, you can buy your own potion, or you can buy it very well. You have no idea what potion it is for you in the hair salon. You bought a potion, and then you went to the store and asked him to process it for you, that is, straighten it. The processing cost of your wool is almost the same 10 yuan.
If you go directly to the store to get it, to be honest, few people ask you to buy a bottle of straightening medicine. They all set the price according to the amount of your hair.
Finally, if it's just bangs, generally the first step can be softening. However, if your hair is hard, it will curl back after softening for a few days.
In fact, you can do it yourself at home, find a classmate to help you, buy potions, splints (you can buy them within 30 minutes), small brushes and small bowls, and pull them if you want.
