A hair style that appears to defy the laws of physics and reality. There are various subcategories for this:

* [[Single hair bun]]s or [[double bun|double buns]] that are so large that the character's head should be weighed down (post #1252821)
* Hair that does not properly fall when a character is upside-down (post #1665007, post #3782951)
* Long hair that should fall due to gravity yet somehow does not (post #4294423, post #4051295, post #3976910)
* Hairstyles that are not realistically possible (post #1376763, post #1636140, [[hair ears]])
