Hairstyling can be frustrating. We all know that feeling when your hair refuses to cooperate and takes on a life of its own when you try a slicked-back glam. The comb won’t comb and your hair keeps getting messy no matter how hard you try to get rid of those stubborn bumps on your crown.

The first thing that comes to mind is to start over. But what if we told you that there is a chance to fix your hairstyle without actually redoing it? Sound strange? Then check out this viral hair hack using a bobby pin to tame your locks for a sleek look.

Yes, you heard that right. All you need is a tiny bobby pin that’s probably lying around at the bottom of your bag. Slide the pin under a bumpy section of your tight ponytail by holding the tool flat against your scalp. Then, gently slide a bobby pin through your hair, from front to back as if you were pulling the strands out from under your hair.

And just like that, with this simple move, all the bumps magically disappear, leaving behind a smooth hairline. The bobby pin essentially moves the bumps to the base of the ponytail, making them easier to hide. Hair fanatics are loving this trick, and are thanking the TikTok creator in the comments. “YOU’RE MATTERING, where were you when I was in high school?” one person writes. “So you’re telling me I didn’t have to do it 1000 times and hit myself with the brush and cry,” another follower adds.
