Long hair side fades, a type of haircut characterized by long hair on top that gradually fades into shorter hair on the sides and back, have become increasingly popular. For instance, the "disconnected undercut," a modern variation of this style, features a sharp contrast between the long top and shaved sides.
This haircut's versatility and ability to complement various face shapes contribute to its popularity. It allows for experimentation with different hair lengths and textures, offering a tailored look. Historically, the style emerged in the mid-20th century as a deviation from traditional short haircuts.
