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

Backcombing is a technique specifically designed to create volume at the roots of hair. It involves gently teasing or combing the hair near the scalp, which lifts the hair and creates height and fullness. This method is particularly effective for adding body to fine or thin hair and is often used in various hairstyles to achieve a more voluminous look.

While flat ironing is primarily used to straighten hair and create sleek styles, and blow drying can also add volume when used with the right techniques (like lifting the roots while drying), backcombing directly targets the root area for maximum volume. Hair curling, on the other hand, primarily adds waves or curls and generally focuses on the mid-lengths and ends rather than the roots.
