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

Backcombing is a technique specifically designed to create volume at the roots of hair. This method involves using a comb to tease the hair near the scalp, which lifts the hair strands and creates a fuller look. The process works by tangling the hair fibers together, providing lift and structural support at the base of the hair where volume is desired.

While blow drying can also contribute to volume, it typically does not create the same kind of lift at the roots as backcombing does. Flat ironing and pin curling serve different purposes, with flat ironing primarily straightening hair and pin curling being used for creating waves or curls rather than focusing specifically on root volume. Thus, backcombing is recognized as the go-to technique for achieving root volume effectively.
