Hairpin is an unlockable trinket added in The Binding of Isaac: Afterbirth † (Booster Pack #1).
Effects[ | ]
- Fully recharges Isaac's active item upon entering an unexplored Boss Room.
- This effect only occurs the first time a Boss Room is entered; leaving and re-entering the Boss Room will not result in more recharges.
Notes[ | ]
- If there are multiple Boss rooms on the same floor (Curse of the Labyrinth, The Void), the trinket's effect will trigger once for each and every Boss Room.
- In Greed Mode, grants a full charge only for the two boss fights on the final level.
- Cannot appear in Greed Mode, though will function the same if accessed through the Debug Console.
- Recharges twice on Corpse II: 1st time happens when entering the boss room, 2nd time happens when entering the Mother fight.
- Does not fully recharge between Dogma and The Beast.
Synergies[ | ]
- Jacob's Ladder: Increases arcing distance of sparks.

- The item will gain both its charges.
- Mega Blast: Mega Blast gains only 3 charge units, unlike all other 12 room recharge items, who are fully charged.
