How to Pin Back One Side of a Bob
A bob does not need to reach a ponytail to feel styled. Moving one small front section away from the face can create a clear asymmetrical shape while leaving the haircut visible. This guide uses a single side section held close to the head with a pin or a small barrette. It is intentionally different from trying to collect every short layer into an updo. Start with the side you naturally tuck behind your ear, then decide whether the fastening should be a visible detail or a quiet support.

Best suited to: Best starting point: a bob with a front section long enough to tuck or guide behind the temple. Very short layers may need a smaller section.
What you need
- One or two smooth bobby pins with intact protective tips, or a small lightweight barrette
- A comb or fingers for defining the part
- A mirror showing the side of the head
Step by step
- Set your usual part and arrange the rest of the bob. Choose the side to pin by seeing which front section reaches back easily. If you use a deeper part, the heavier side can make a more visible sweep, but it also needs a fastening that holds that amount of hair.
- Separate a narrow section near the temple. Keep the line simple and leave very short fringe pieces out. Begin with less hair than you think you need; you can enlarge the section once you know the fastening works.
- Guide the section backward along the side of the head. You can keep it flat or give it one loose twist away from the face. Hold it at the point where it naturally reaches instead of stretching it to the back of the ear.
- Place a bobby pin across the section so it catches both the selected hair and a little hair beneath. Slide it in with the closed tip leading, keeping it nearly parallel to the head. Do not scrape along the scalp to make it grip.
- If using a barrette, open it fully, place the section inside and close it only if the latch engages easily. A bulging section that prevents the latch closing should be made smaller. Do not use the clasp as a lever to compress the bundle.
- Remove your holding hand and look at the outline from the front and side. If the section springs free, reset with less hair or move the fastening slightly forward. If you need a second pin, position it to support a loose edge rather than stacking blindly.
- Check that the fastening does not touch the arm of your glasses or catch on an earring. To remove it, hold the section steady and slide the pin out along its entry path. Open a barrette fully before drawing it away from the hair.
Let the haircut set the limits
A blunt bob often has a longer front section than a heavily layered bob of the same overall length. That changes where the pin can sit. If the section stops at the temple, make that the fastening point instead of chasing a position behind the ear. Wavy or curly bobs may look best when an existing wave or curl group is moved as a unit. There is no requirement to brush the whole side smooth. On very fine hair, a small section and a light fastening usually create a more proportionate result than a heavy decorative clip.
Make the pin visible on purpose
A dark pin on dark hair can be discreet; a contrasting pin becomes part of the design. Both choices are deliberate, so you do not need to hide a pin by placing it uncomfortably close to the scalp. If using two visible pins, align them with the sweep of the section and leave enough space to release them easily. This guide does not require the pins to cross. Crossed pins can hold some arrangements, but they are not a substitute for choosing the right section size and a pin that still grips.
Solve slipping and bumps
A pin that opens easily but never closes firmly may be worn out. Replace it instead of bending it repeatedly while it is in the hair. A bump near the front can appear when the section is folded at a sharp angle; release it and make a broader, gentler sweep. If the pinned side looks too flat compared with the other side, loosen the section or move the part before fastening again. Keep the edit small: a side pin is meant to complement the haircut, not erase every bit of its natural shape.
Your quick checklist
- The section reaches its fastening point naturally.
- The pin tips or clasp are intact.
- Glasses and earrings move without catching.
- The rest of the bob keeps its intended shape.
Common questions
Which side of the bobby pin faces the head?
Many standard pins have a ridged side designed to grip close to the hair. Follow the shape of your particular pin and place it comfortably; the important points are secure contact and no scraping.
Can I pin wet hair to set a shape?
This guide is a dry-hair styling method. A drying or setting routine needs different preparation, and leaving a hard pin in while resting is not part of this tutorial.
What if the pin catches my glasses?
Move the section and fastening above or forward of the glasses arm, or choose a smaller barrette. Check the fit with the glasses on before leaving the mirror.
