Securing hair: Bobby pins can be used to secure hair and keep it neat and tidy. For example, when combing a ponytail, you can use a bobby pin to secure the end of the hair so that it does not fall apart.
Decorative hair: Hair clips can be used to decorate a variety of hair styles, increasing the beauty and fashion sense of hair. For example, in the updo, you can use bobby pins to fix the bun to make it more firm and beautiful.
Fixed headgear: Hair clips can be used to secure headgear, such as headbands, headbands, etc. This will make the headgear more firm and not easy to fall off.
