For most curl styles, you should not brush your hair after removing the curlers. Instead, use your fingers to rake through the curls lightly and separate them. There are, however, some looser curl styles that require brushing after the rollers have been removed. This will generally elongate the curls and create a lot of volume. If you brush your hair, ensure that it is dry and cooled down. Brushing your hair before it has cooled or dried completely will straighten out most of the curls you’re trying to create. If your hair is still slightly damp, use a hair dryer diffuser to dry the curls fully.
