Hair that is arranged so that the cuticles of all hair strands slope in the same direction is referred to as turned hair. This arrangement is vital because it helps maintain the integrity and appearance of the hair. When the cuticles face the same direction, the hair is less likely to tangle and will also have a more natural look and feel.

Turned hair is often preferred for extensions and weaves because it behaves more like natural hair, allowing for smoother styling and a more seamless blend. The alignment of cuticles also reduces friction during washing and styling, which can help to minimize damage and prolong the lifespan of the hair.

Other options do not accurately describe this specific arrangement. Processed hair refers to hair that has undergone treatments such as coloring or perming, which do not inherently affect the cuticle direction. Fallen hair typically describes natural shed hair which may have cuticles that are mixed in direction. Resistant hair refers to hair that is difficult to color or style but does not relate to the alignment of the cuticles. Therefore, the distinction made by the term "turned hair" highlights its significance in providing a higher quality end result in hair applications.
