18. The Rachel: Unless you lived under a rock in the mid-1990s, you knew about the group of Friends that hung out on the NBC sitcom for ten seasons. Jennifer Aniston's character Rachel spawned legions of hair clones. This long- to medium-length style was cut with many different layers in order to frame the face and give a woman's hair a full, healthy look.
19. The Fade: The early 90s brought hip-hop culture to the masses and the high-top fade haircut came with it. Popularized by rap duo Kid 'N Play, the fade was cut like a flattop but with the sides and back gradually fading from thickness at the top all the way to bare skin. Largely sported by African-American males, men of all ethnic backgrounds gave it a try, often with mixed results.
