What technique is commonly used to achieve volume in hair styling?

Backcombing or teasing is a widely recognized technique for achieving volume in hair styling. This method involves combing the hair towards the scalp in a way that creates a fluffy, voluminous look. By lifting the hair strands upward and creating a tangle near the roots, backcombing adds texture and body to the hair, making it appear fuller. This technique is particularly effective for fine or limp hair, which may struggle to hold volume naturally.

Other options present different hairstyling techniques, each with its own purpose. Straightening primarily focuses on creating a sleek and smooth look, which typically does not enhance volume. Blow-drying can add some volume, especially when combined with specific techniques like using a round brush, but it may not achieve the same level of height and structure that backcombing provides. Layering involves cutting hair at different lengths, which can give the appearance of volume but works differently from backcombing. In summary, backcombing stands out as a direct method for enhancing volume, making it the most appropriate choice in this context.
