What is Bobby Pin Styling?
Last updated 2026-06-15
The bobby pin was invented in the 1920s to secure the bobbed hairstyles that defined the era, and its basic design — a crimped, U-shaped wire with one straight and one wavy side — has remained largely unchanged for a century. The wavy side grips the hair while the straight side sits against the scalp, creating friction-based hold without the bulk of larger clips. Traditional bobby pin technique focuses on invisibility. Pins are inserted with the wavy side down, slid close to the scalp, and concealed beneath overlapping hair sections. This approach supports updos, secures braids, tames flyaways, and anchors heavier accessories without being seen. Professional stylists consider invisible pinning a fundamental skill — a well-pinned updo should show no hardware at all. The decorative bobby pin trend inverted this logic entirely. Starting in the late 2010s, designers and stylists began intentionally exposing bobby pins as decorative elements. Pins arranged in X patterns, parallel lines, geometric shapes, or criss-cross formations became a deliberate style statement. This spawned a market for decorative bobby pins in gold, silver, rose gold, and adorned with pearls, crystals, enamel, and charms. Effective bobby pin placement follows hair growth patterns and gravity. Pins inserted against the direction of hair growth hold more securely. Crossing two pins in an X creates a stronger anchor point than a single pin. For heavy hair sections, inserting the pin, then pushing it slightly back toward the scalp and forward again creates a zigzag grip that dramatically increases hold. Opening the pin slightly before insertion — rather than trying to slide it in fully closed — also improves grip.
Hairstylist Yuki created an editorial look using nothing but twenty gold bobby pins arranged in a sunburst pattern radiating from a low bun, proving that the simplest, cheapest hair accessory could produce a result as striking as any designer headpiece when placed with intentionality and precision.

Questions, answered.
Why do bobby pins slide out of some hair types?
Bobby pins rely on friction between the wavy and straight sides to grip hair. Very silky, freshly washed, or fine hair has less natural texture for the pin to catch. Solutions include inserting pins into slightly textured or dry-shampooed hair, spraying pins with hairspray before insertion to increase grip, using pins that match your hair color for tighter camouflage, and always inserting with the wavy side against the scalp. Pins with textured or rubber-coated tips also grip smoother hair more effectively.
How many bobby pins do you need for an updo?
A simple twist or small bun typically needs four to eight pins. A French twist requires eight to twelve. An elaborate bridal updo may use twenty to thirty or more. The key is using enough pins for security without overloading — too many pins in one area actually reduce hold by preventing any single pin from gripping properly. If you find yourself needing excessive pins, the underlying structure may need a different approach, like a foundation of elastic or a foam donut for volume.
