Using a round brush during a blow dry is an effective technique for creating volume at the roots. The round brush allows for the hair to be lifted away from the scalp as it dries, which enhances the volume and creates a fuller appearance. When the hair is wrapped around the brush and then dried with a blow dryer, the tension and the round shape of the brush work together to boost the roots, providing that desired lift. This method also helps in shaping the hair and adding bounce to the style.

Other techniques, such as flat ironing, are typically used to straighten and smooth hair rather than to create volume. Pin curling does provide some volume but is a styling method that is not directly related to blow drying. Blow drying straight refers to the process of drying hair without specific styling techniques and may not involve the added volume that a round brush provides. Thus, using a round brush is the most effective method for achieving root volume during a blow dry.
