You can do some curling. If it is only a small part of hair, you can generally wrap your fingers around your fingers in the direction you want after washing your hair, and blow your hair in the direction of curling with a hair dryer. When the hair is about to dry, you can also use hair wax or other styling gel to curl your hair by hand at will, so that you can do it yourself at ordinary times. If many places need curling and you can't do it yourself, you can go.
