Liu Hai is fine ~ It doesn't need much modification ~ If you don't want a bob, it's recommended to cut your hair above your shoulders ~ Scalp the back of your head with corn ~ or roll it ~ It doesn't take much time in the morning ~ Just grab it and go out ~
If you don't want to cut it ~ perm it ~ it will cover the back of your head ~ your hair will be fluffy ~ naturally it won't feel flat ~
