Which technique is used to create volume at the roots when styling hair?

Teasing, also known as backcombing, is a technique specifically designed to create volume at the roots when styling hair. This method involves using a fine-toothed comb to lift sections of hair away from the scalp, creating a fluffy, voluminous effect. By combing hair towards the roots, teasing tangles the hair strands and gives the appearance of increased body and fullness. This technique is particularly useful for achieving styles that require added height and volume, such as updos or when creating a dramatic look.

Blow drying can enhance volume indirectly by adding lift when used with the right techniques and tools, such as a round brush, but the primary method for directly increasing root volume is teasing. Smoothing generally refers to creating a sleek and polished look, which tends to reduce volume rather than add to it. Braiding is primarily a styling technique that can create texture but does not focus on creating volume at the roots.
