What affects the volume achieved by roller placement?

The volume achieved by roller placement is influenced by both the size of the roller and its position on the hair. The size of the roller determines how much hair is wrapped around it, directly affecting the amount of curl and volume created. Larger rollers will create looser, more voluminous curls, while smaller rollers will produce tighter curls, which can also contribute to volume, but in a different manner.

In addition to roller size, the position in which the roller is placed also plays a crucial role. For example, placing rollers at the base of the hair will create more lift and volume at the roots, while rolling the hair horizontally or diagonally could result in different shapes and sizes of curls, affecting the overall volume and appearance. By understanding how both the size of the roller and its positioning impact the hairstyle, a cosmetologist can achieve the desired volume and style for their clients.
