Sci-Fi Bob Haircut

There's something about the clean lines of a bob, particularly with bangs, that suggests a sci-fi setting. Despite the style dating back to the twenties (and being the defining hairstyle of the timeframe), they are still seen as a little bit rebellious and progressive. After all, Long Hair Is Feminine, so short styles can be shorthand for a more gender equal society. Additionally, the simple, straight lines fit in well with an Ascetic Aesthetic, marking the character as belonging to that timeframe. Not to mention, short hair tends to cause fewer problems with zero-g, helmets, and space suits.

Unlike its Sister Trope the Twenties Bob, Sci-Fi Bobs are almost always mathematically straight edges and hair without curls. Fashionable Asymmetry is also common, one side of the bob being longer than the other.

  • Chiana and other female Nebari from Farscape combines this with White-Skinned Space Babe. Like Leeloo, it's a bit more messy than typical for the trope, but Farscape (which takes place in the present day, only far from Earth) does does have a Used Future aesthetic.

    • Lt. Saavik defies the trope in Star Trek II: The Wrath of Khan, wearing her hair long.
      Kirk: Lieutenant, are you wearing your hair differently?
      Saavik: It is still regulation, Admiral.
    • A non-Vulcan example: Ro Laran in Star Trek: The Next Generation.
    • Dr. Beverly Crusher from The Next Generation has rather long red hair most of the time, but she bobbed her hair for one season.
    • Android Lal was created by Data as a blank slate, even in terms of species. Lal chose to look like a young human woman with pale complexion and black hair in a short sleek bob.
    • Carol Marcus in the rebooted series, starting with Star Trek Into Darkness.

  • Red Dwarf: The AI computer Hilly (she's just a head on black screen) from "Parallel Universe" wears Sci-fi Bob Haircut. In the third season, she became a regular when the crew's computer Holly decided to take her likeness and make a gender swap. In the later episodes, however, her hair was longer.

  • Whoniverse:
    • In Doctor Who, Zoe Heriot has this as a science-minded companion to the Second Doctor, who he met in a space station in the future.

  • Several characters of both genders in the Honor Harrington series are described as having shorter hair than is strictly fashionable, ranging from a bob cut all the way to shaved heads, specifically because loose hair floating around in a zero-g and/or industrial environment can be both inconvenient and potentially dangerous. On the planet Masada, male spacers (there are no female Masadan spacers) can be easily identified by their short hair and clean-trimmed facial hair, in contrast to everyone else having long hair and beards.
  • Benny Summerfield, of 'Doctor Who New Adventures' and later her own series started with short hair, and subsequently seems to have grown it out to about bob length.
