Hair design primarily results in a temporary change in which of the following?

Hair design primarily results in a temporary change in form, texture, and direction. This is because hairstyling techniques such as curling, straightening, and shaping manipulate the structure of the hair to create different styles that can be adjusted or undone. Unlike permanent changes like color or the actual length of hair, the modifications made through hairstyle can be reverted, allowing for versatility in looks without altering the hair's inherent properties permanently.

Form refers to the overall shape and silhouette of the hairstyle, texture pertains to how the hair feels, whether it is smooth or frizzy, and direction involves the orientation or flow of the hair—whether it is styled upwards, downwards, or in various patterns. This flexibility is a fundamental aspect of hairstyling, enabling individuals to express themselves through their hair on a temporary basis.
