Hairpins (or bobby pins) are one of the most common items in bathrooms and handbags around the world. They’re cheap, tiny, and often taken for granted — but did you know most people have been using them the wrong way their entire life?

🎯 The Purpose of the Wavy Side

Most people slide a bobby pin into their hair with the wavy side facing out, thinking the curves are for decoration or grip on top.

🛑 That’s actually backwards.

✅ The correct way to use a bobby pin is with the wavy side facing down, against your scalp.

Why?

• The waves help grip the hair better and prevent slipping.

• The flat side acts like a smooth anchor to hold everything in place.

• It results in tighter, more secure styling.

This small adjustment can completely change how effective the pin is, especially for holding up buns, twists, and updos that normally fall apart.
