In either a gunfight or a sword battle, sometimes the bullet or blade gets just a bit too close for comfort, and you often see a Close-Call Haircut with a few cut strands of hair blowing around to indicate just how close the character came to getting hit. The character may even quickly run a hand through their hair and watch loose strands float away in the wind as confirmation. May also mark the point in the battle when the gloves come off, especially if one or both of the fighters are female and it suddenly becomes personal as soon as the female character's beauty is involved.
A common variation involves a bullet passing through a female character's hair, creating a gaping hole that's sometimes magically repaired by the next scene (see Hair Reboot).
May overlap with Important Haircut or Traumatic Haircut in some cases. See also Slipknot Ponytail and Hat Damage. Compare Losing a Shoe in the Struggle when the same effect is achieved with a minor article of clothing instead.
The trope was popularized during the Renaissance, when sword-wielding folk moved away from large and cumbersome cutting tools to lighter weapons that allowed additional finesse. Trimming an opponent's mustache or removing buttons in a declared order was a way to demonstrate one's superior fighting skills whilst simultaneously humiliating your opponent, culminating in the famous 'slice your initial in your opponent's clothes without actually breaking his skin' maneuver made famous by Alex Thoth's Zorro.
