Wedge haircuts are a great choice for someone with fine hair, according to Marie Claire. Because of its similarity to a bob, a wedge cut leaves maximum volume at the base of the cut, making fine and thin hair appear thicker. Wedge cuts also create a great deal of movement.
Although sometimes used interchangeably, the terms "fine" and "thin" refer to different properties of hair. Someone with fine hair possesses hair strands that are smaller in diameter than someone with coarse hair. However, thin hair refers to the number of hairs sprouting from one square inch of the scalp. Thin hair has fewer hairs per square inch than someone with thick hair.
