A long layered haircut is one of the most effective hairstyles for square face shapes. This style introduces soft layers throughout the hair, which help reduce the emphasis on sharp facial angles. The layers create movement that frames the face gently rather than forming straight vertical lines.

The concept behind long layered hair focuses on distributing volume across different sections of the hair. Instead of allowing the hair to fall in a single heavy length, layers create a gradual flow that softens the appearance of the jawline. This effect is especially beneficial for square faces because it reduces the visual strength of the lower face.
