Bobby pins. The go to pin for holding any up do in place. But are you using them correctly? Apparently, the correct way to use a bobby pin is to turn it so that the wavy side is parallel to your scalp. Using them in this way means the pin can get more grip on your hair so that it stays in place and so holds your style for longer too. But do your bobby pins keep falling out of your hair? Perhaps it’s time to replace your old pins with some new ones. Over time, as you separate the slide this can cause them to lose their grip from spreading them apart, making them less effective.
