Up until very recently, I’ve been doing it wrong. Did you know there is correct way to wear a bobby pin? Take a look at the picture. For better grip, you are should flip the bobby pin over so that the wavy side is against your head. Flipping them over, helps if you have a hard time keeping your bobby pins in place. The straight side is slicker and won’t grip as well as the wavy, more textured side.
Yeah, I know it’s mind blowing.
