This sounds like a classic clickbait title, the kind you often see on YouTube or TikTok! It usually says: “99% of people use bobby pins wrong!”

The supposed “secret” that’s then revealed is actually just a simple but practical application trick:

The bobby pin’s “secret”:

The ridged side goes down: Many people insert the bobby pin with the smooth side facing their scalp. But the correct way is exactly the opposite: The ridged side points downwards (towards the scalp).

Why? The ridges in the pin are there to grip the hair and secure the curl or strand. The smooth side on top ensures a cleaner, flatter finish. In addition, the slight bend at the end prevents you from scratching your scalp.

Three more real pro tricks for bobby pins:

The hairspray trick: If the pins keep slipping out, spray them with a little hairspray or dry shampoo before inserting them. This gives them extreme grip.

The “X” mantra: For a rock-solid hold, cross two bobby pins in the shape of an “X.” They lock into each other.

Don’t bend them open: If you bend the bobby pin open too far before inserting it, it loses its tension and stretches out. It’s best to just push it directly into your hair.
