What technique is used to create volume at the roots of the hair?

Backcombing, also known as teasing, is a technique specifically designed to create volume at the roots of the hair. This method involves gently combing the hair backwards towards the scalp, which creates tangles and lifts the hair upwards. This lift contributes to a fuller appearance, making it a popular choice for styles that require added volume.

While blow drying with a round brush can also enhance volume, it often focuses on the overall smoothness and shape rather than specifically targeting root volume as effectively as backcombing. Flat ironing, on the other hand, is primarily used for straightening hair and does not contribute to volume at the roots. Using hair gel for hold serves different purposes, such as providing hold or texture, but it does not create the lift needed for root volume. Thus, backcombing stands out as the most effective technique for achieving the desired height and volume at the roots.
