Which technique creates height and volume at the base of the scalp?

The technique that creates height and volume at the base of the scalp is back-combing. This process involves teasing or combing the hair toward the scalp, which lifts the cuticle and creates a cushion of hair. As a result, it adds body and fullness, making it an effective method for achieving significant elevation at the roots.

Back-combing can be particularly beneficial in styling, as it helps to create dramatic looks by allowing the hair to stand away from the scalp, giving a voluminous, styled appearance. It’s a commonly used technique in various hairstyles, especially in updos and voluminous styles, as it provides control and structure.

Other techniques mentioned in the options have distinct purposes; for example, back-brushing also adds volume but is typically used for smoothing and refining hair rather than creating the initial height. Cascade curls and barrel curls are primarily styling techniques that create waves or curls in the hair rather than addressing volume at the base directly. Thus, back-combing stands out as the method focused on enhancing height and volume right at the scalp area.
